A podiatrist recommended a specific Vionic sandal which he felt would support my painful feet. After two years of wonderful comfort from the pair I bought, I’ve just bought four more pairs in different colours. Is that satisfaction or what!

this waz


This is my 4th pair of shoes from vionic love them all



I have bad feet, and they are v comfy



I bought the Rio sandals a few weeks ago and they are very stylish and comfortable for my extra wide feet. I love them! This is my third pair of Vionic sandals. They support my ankles, relieving pressure on my arthritic knee, enabling me to walk for longer than other brands of shoes that I own. I wouldn’t like to be without them.



i got these a week ago, as i have problems with my feet great job



I'm so pleased with my new shoes. I'd worn my old vionic sliders into the ground so it's great to have another pair. These are really comfy and look good. Even more important is that they support my feet properly.
Size is just right. I'm a 7.5-8. Bought 7as advised and they fit perfectly.



Having suffered for years with fallen arches and a torn planta fascia, I discovered this company and can honestly say they are the best sandals and perfect for my feet. I can wear them all day with no pain at all. Excellent service from Vionic too. I had to return my first pair and within 3 days another pair arrived! My go to shop for all my new shoes!



This RIO sandals are the best, I can walk all day without pain in my feet, for plantar fasciatis are the excellent. Highly recommend this sandals. Please never remove from the market.



Bought this thinking bet it will not fit because i have wide feet but i will try. Anyway glad i did they are lovely, couple of wears and they are me .



Great shoes nice and wide , I didn’t like the cross over strap but loved the sandals so I cut the strap off and have had loads of people ask where I got these from ! Anyway a great sandal very comfortable easy on easy off .



So comfortable to wear even with my foot problems.
Vionic shoes have been a great find .



These sandals are very comfortable, and have helped an Achilles issue I have. Would love to buy more from the range, but they are quite expensive so I’ll need to save up - hence the 4 stars rather than 5.



Finally I found nice sandals that help me manage pain in my foot and look lovely. Thank you soo much. I bought three other pairs of shoes from Vionic After this purchase and soo happy with all, I will never wear any other brand of shoes!



I brought these a few weeks ago and after a taking a few days to get use to waring I notices my hips and knees felt better and my arches where supported much better. I really notice the difference now when I ware my old shoes with my feet and hips hurting after a hour.. I ware them all the time round the house and will defiantly get another pair soon.



Amazing sandles, I have Posterior Tibia Inflammation and damage from broken ankle from years ago which is causing problems. These sandles have been a god send for me as I can wear them without pain under my foot and ankle.



These sandals are so comfortable for wearing all day and very good value. The service and delivery as usual was first class.



These sandals are really comfortable but could do with a bit higher here as that makes it more comfortable for walking in this is my fifth pair Of Vionic sandals



I got these on the sale, and am about to order in another colour. I suffer from plantar fassiitis real bad and usually buy insoles with a raised arch, but they are no good for sandals as they move about. Then after a lot of research I found VionicShoes. From now on, they will be the only shoes I buy, all my old ones are going to charity. Extremly satisfied.



absolutely love them.Really comfy and stylish



Very comfortable, just like slippers which I use them for and have a good arch support. I wear them all day indoors. Great help in supporting my feet.



I have been struggling for years with unsatisfactory insoles and ill-fitting shoes, and no sandals for the summer! These Rio sandals have changed my life - I can walk with confidence. Only mild complaint is that I have a bit of a struggle to put them on

Reorder of an old favourite. These never fail to provide comfort and important arch support. Have bought these three times now In different colours and quality is always good. They last for years too!



Love these sandals they are so comfotable but also look good. Feels like your wearing slippers , don’t want to take them off. Great for the summer



I have a couple of pairs of shoes, sandals and trainers. These shoes were very comfortable from the get go. I have arthritis in my knees and Vionic’s help to align my posture and relieve some of the pain.



I purchased these lovely red sandals as they were in the sale, I wanted something that would give me at Support and these are my first pair of Vionic’s.

They are extremely comfortable and absolutely lovely shade of red and I wear them every day. I even purchased a pair for my friend and she loves them tooI purchased these lovely red sandals as they were in the sale, I wanted something that would give me at support and these are my first pair of VIonic‘s.

I have no hesitation in recommending them for arch support and comfort.



So happy amazing service and best sandal I have worn.



I have some vionic summer walking shoes which are great but fot the winter relied on arch support insoles from elsewhere in ordinary walking shoes, never again! I bought flat and heeled sandals recently and cannot believe the difference it has made to the leg and hip pain I was getting. My body feels re aligned. Highly recommended

This is the second pair of Rio I have bought. They are so comfortable and have really strengthened my feet in light of plantar fasciitis. I wear them all day around the house. I would highly recommend Vionic to anyone with the condition. So nice to have glamorous footwear that is beneficial.



These sandals are a revelation. All straps are adjustable and the foot bed is perfect for my feet.I have rheumatoid arthritis and my feet vary in size from day to day so the adjustability is key.Also they are fashionable



Bought 2 pairs of these mules and keep one just to wear as slippers indoors. The ease the terrible pain I get in my heel. Lovely and comfortable and a good fit as they have adjustable straps. The soles are not rock hard...they are just the right density.
All in all a very comfortable sandal and a great bargain in the sale (as they are a bit pricey full price).



I'm usually a size 5.5 in vionics. Prefer wide fit for winter boots etc to accommodate socks & for sandals to allow for feet swelling. Standard for all else.
Found these to be long in length so my foot slipped forward & arch therefore in wrong place & very wide although adjustable.
I really loved the look of them, red with red toenails perfect,but not for me sadly. Given to my size 6 daughter whom they fitted perfectly & declared even more comfortable than her Vionic flip flops.

These sandals are a lovely colour and initially very comfortable though on wearing them for a length of time I found that the topstrap rubbed my foot as it sits rather high. However I wouldn't dream of returning them as I got them at a good price in the sale and I like the look of them. I just have to remember not to wear them for too long!



Very comfortable from day 1, true to size (seems hit and miss with Vionic). Perfect for travelling and great to wear every day. And red!

Received these sandals have had Vionic sandals before .i have a broad foot so easy to adjust come up quite big in size I normally take 41/2 so bought a size 4 (37) but there is still a slight gap from my foot and end of sandal but size (36) would have been too small just be aware of this when buying .Its better to be slightly too big than too small .They look very nice and will be great once I get used to them again .



My second pair puppy ate the pair I bought last year they are brilliant.Although they are a wide fit and I have really thin feet they can be adjusted so they fit perfect very good for your feet



There is something about red shoes, well now I can go over the rainbow too and they go with every outfit . Perfect thanks .



After reading reviews about Vionic shoes decide d to invest in it as I suffer from plantar facilitis.
Since it was sale bought it as house shoes. Would love to buy a pair for work to get the full benefits As I am on my feet all day. Only thing is too expensive ☺️



I am never disappointed with a purchase from Vionic , these sandals are a perfect fit and what a bargain



Very good quality product at a reduced price.

i have suffered from plantarr fascittis for a long time and these sandals are just so wonderfully supportive .
i feel as light as a feather .they are light ,snug fit and overall worth every penny.



I have very wide feet as well as a high instep so you can imagine my delight to be able to take these out of the box and say 'they fit'.
The relief I got from the pain of plantar fasciitis was almost instant.
Adjustable velcro straps remain secure.
Buckle has an elastic attachment for additional comfort.
Definitely had to wear them for a few hours each day until my feet got used to them.
Sizing true for me.
Fast, free delivery.
Have since bought the 'Amber' sandals and love them as much. Now waiting on a sale to make another purchase ...



I Loved the look of these retro wedges, and they have proved to be every bit as good as I hoped, really good looking as well as comfy, top marks!

With a young active baby and constantly being on feet at times by the end of the day I was in so much pain eventually when sat down or resting for the day. Bought these sandals and they are absolutely amazing and what the tin says...I can now be on my feet and feel comfort, zero pain and still run around an active baby. Thank you



I purchased these lovely red Rios mainly because they were a reduced price and I wanted to try Vionics. I am not disappointed - they are a gorgeous red and very comfortable. As I have 42/8 wide feet and now plantar fascitis I didn't think I would be able to wear summer footwear comfortably again without orthotic inserts. I must also praise the speed in which they arrived - just over 24 hours and in lockdown - and free postage - faboulous thank you very much ..... now off to order another style.



These are my second pair in another colour love them they are wide enough and support my feet where I need on my soles of my feet love them and when I see in the sale I'll have another



I ordered these Rio shoes in red mainly because they were in the sale and I wanted to try Vionics. I have size 42/8 wide feet, and have recently been suffering from Plantar Fascitis - I really thought I would be stuck wearing trainers with my personal orthotics. Well I am SO happy the sizing was brilliant on these shoes, they are a fab colour, and really comfortable. I have worn them inside the last couple of days to get used to them and am so pleased. To make things even better - I ordered them thinking they would take a while in lockdown and they arrived within two days and no postage was paid. Five star service and five star shoes. I can't wait to try another style now.........



Really lovely, comfortable sandals. I particularly like the elevation they give you. I have an almost identical pair which are a flatter sole but the straps are made of leather which I much prefer. I also need to add that I have wide feet an d they’re perfect, with every strap being adjustable.

I already have these sandals in white and i find them so comfy, so hubby bought me a pair to cheer me up and i have to say they look great with anything and all adjustable i just love Vionic.



I bought these shoes a month ago .I love them . So comfortable.Have in two colours now and many more vionic shoes



I have wide feet and these are adjustable, super comfy would definitely recommend.

tess shoe mad


I bought these in red i already had a pair similar in white and love them so got a new pair ready for when lock down will be over ....but wearing them at home at the moment i love all Vionic ..they arrived quickly and were packed well great stuff oh and the sale price was even better.



Love Vionic for quality and comfort



I’m really happy with my sandals & have noticed a difference with the pain I have from planter fasciitis. Very comfortable to wear & I will be purchasing more soon . Thank you



I love owning a pair of red shoes! These Vionic ones are comfortable and look good. Good price too.



I bought these to replace an old pair of slides as during lock-down that's all I want to wear around the house. These are so comfy and supportive and look as is they will last and last. I need the arch support Vionic offers and find it hard to get anywhere else. Oh, and I got an amazing bargain too! Thanks.



Very pleased with the purchase of these shoes. Very comfortable, just what I needed. Thank You



I bought these a few weeks ago and I am very happy with them. I particularly like the raised arch. At the age of 63, I find I have to wear shoes with raised arches to try to keep my feet in the right shape and I use these clog type shoes in the house as a type of slipper. You can adjust the tightness across the feet by adjusting the three straps.



This sandal fulfils my expectations of comfortable, attractive summer footwear. Vionic footwear is extremely comfortable and the pain from plantar fasciitis has quite disappeared. I can now walk miles without discomfort and have recommended Vionic to several of my friends who have all been delighted with their Vionic footwear.



Was recommended Vionic shoes by a friend as I have Plantar fasciitis. In the space of 4 weeks I have purchased 3 different pairs of Vionic shoes. Rio were the first purchased along with some slippers. I cannot tell you how much these have changed my life! Would definitely recommend Rio sandals. The prices are very reasonable when you take into consideration the cost of buying separate insoles for shoes, I paid £35 for a pair which are only suitable for full shoe or boots, and, did not help as much as Vionic’s! Before Vionic’s I was in agony towards the end of the day and the pain was unbearable! These have changed my life completely, I can now, as I used to, spend a lot of time on my feet and absolutely no pain! Can’t thank my friend enough for telling me about Vionic shoes! I am a 5 1/2 normally but as advised ordered half a size down and perfect fit! The 2 pairs of sandals and the slippers I have purchased all from the first try on are so comfortable. It’s amazing. Thank you for stopping the pain and changing my life! p.s. I will definitely be purchasing more of these amazing shoes in the not too distant future!



I bought these sandals for summer. They are super comfortable and very stylish. Highly recommended



Bought these shoes, in two shades.. They look nice and have given great relief to a painful condition in my heel.



Bought a pair found them so comfortable because I could adjust the straps, liked them so I much sent for another pair in a another colour.

Ironing lady


I’m buying more in different colours!



Previous review and description state that these are not suitable for narrow feet, I don’t consider myself to have narrow feet but these sandals were extremely wide and so I had to return them.
I have a lot of Vionic sandals but these were probably the cheapest looking ones I’ve come across, had I seen them in a shop I don’t think I would even try them on.
Sorry Vionic love your shoes normally but didn’t think these were up to the usual standard.



Very comfortable
