Our innovative podiatrist-designed FMT Technology provides superior orthotic support, relief and stability which helps realign the feet back to their natural position.

Research supports FMT Technology's success in reducing over-pronation, which can help relieve associated common aches and pains, such as heel pain (plantar fasciitis), knee pain and lower back pain.

Fit & Care

  • Available in men's whole sizes 7-12
  • If you are a half size, we recommend ordering the nearest size down.
  • Available in medium (G) widths.
  • Footbed: Irving

For the greatest comfort, we recommend wearing your new VIONIC footwear for just a few hours for the first few days to allow your feet to adjust to the new level of orthotic comfort and support.

Within one to two weeks you should find the product completely comfortable and supportive.

  • To preserve the appearance of your VIONIC shoes, we recommend that you clean the leather, if needed, using a dry, cotton cloth to wipe away dirt or dust.
  • Keep leather footwear away from direct heat to prevent the leather from drying out. If your shoes or sandals become wet, please allow them to dry naturally.
  • We recommend that you test any cleaning product by applying a small amount to a discrete area and allowing it to dry.
  • Do NOT use cleaners which contain acid or detergents, as they may damage and prematurely age the leather.

I have had these for around a month now and I can confirm that they have definitely helped with my plantar fasciitis

P. Riojas


I had found Vionic in my endless search for help due to my constant battles with plantar fasciitis in both feet. I had tried trainers in the past which I found very comfortable to commute all around London.
Due to the above, when my partner said his feet were aching and found his slippers no longer comfortable, I immediately ordered the Adler slippers for him. Needless to say, he found them hugely comfortable and exactly what he was looking for, so much that he asked me to order another pair in a different colour. He is extremely happy and so am I to know he does not have to endure the suffering I had. I gave these as a late Valentine's present!



Very happy with these. Full arch support, and foot correction construction



I bought a pair for my husband and he is delighted with them but they do leave black marks on the hard wood and laminate floors. Easy to remove, just a bit frustrating.



I bought these for my teenage son who is spending lots of time at home online during lockdown and as he has over pronated feet I felt he needed more support. They were expensive for slippers but they are very good quality and will no double last him for ages. What is more he seems to be wearing them when he has never really worn slippers before - so they must be comfortable and he seems to like the styling. He is normally a size 11 but they only had 10.5 so I tried them and they fitted so I would say maybe they come up slightly large.

These are a great pair of slippers. They are very expensive but dare I say that they are worth the money. They are really good quality and very nicely made. I suffered from plantar fasciitis a few years ago and have been w earing orthotic inserts in my shoes ever since so I normally have to go up a size in shoes to compensate for the inserts. The nice thing about these slippers is that the orthotic is built in so no need for an extra insert. Like other reviewers have said, the sole does mark flooring if you drag your feet, I decided to try them anyway and although the do leave some marks on the floor, the marks rub off the floor really easily so panic over. I've noticed this only happens on our vinyl flooring. They are lined with fluffy material which adds to the overall comfort and warmth. They can be worn in or out due to the hard wearing sole, I've even been able to drive very comfortably with them. The only thing that could be improved is the external sole so that it doesn't leave any marks on the floor. Other than that, these are a great pair of slippers. The purchase and delivery options are good and everything worked well. Highly recommended



My husband is very happy with these slippers. He has extremely problematic feet, as a result of having back surgery on three occasions.What a relief to find these, after prolonged searching.
A small problem with one of the laces.It snapped/ broke when first tightened.



Fleece lining combined with proper soles make these perfect for wearing all day in the house and on brief outings to the shops. The arch support means my feet wont lose their shape for when I start rambling again and I dont have to worry about plantar fasciitis



As said I found them very comfortable BUT our dining room and drawing room are wooden, one teak, the other pine. Both floors mark badly from the soles of the slippers. The result being I am banned from wearing them in the house - not ideal. Matt Enticknap



I bought these slippers after reading the many positive reviews . I could not believe how immediate the relief would be when I put on the slippers for the first time..

Lincolnshire Lady


I treated my husband to these slippers as he would never have paid that amount of money. He is pleasantly surprised how comfortable they are and his swollen ankles are much slimmer since he has been wearing them. Worth the money and I'm sure he would recommend them to others.



I bought these for my Husband who has flat feet ,he has said they are the most comfiest slippers he has ever worn






My husband has weak ankles and are easily sprained. I noticed his ankles were both swollen and he already has a pair of trainers so knows how good Vionic is so I suggested he get a pair of slippers.
Of course, he was outraged at paying that much for slippers but I talked him into it.
We couldn’t believe the results. In a few days his ankles had gone right down as well as being so comfortable. He is so pleased he got them. Money well spent!

Having been introduced to Vionic Shoes a few months ago, they are now my number one choice for shoes ect.
The Alder Slipper is without doubt the best slipper I have ever purchased, they are not only stylish, they are very comfortable and good to walk around the house in, at the same time looking after my posture as the slipper includes the Vionic Biomechanical Footbed.
A very very happy and satisfied customer
