Customer Reviews



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.

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.

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
