Fit & Care

  • Available in women's whole sizes 3-9
  • If you are a half size, we recommend ordering the nearest size down.
  • Footbed: Tide

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 sandals, 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 sandals become wet, please allow them to dry naturally.
  • We recommend that you test any cleaning product by applying a small amount to a discreet area and allowing it to dry. Do not use cleaners which contain acid or detergents, as they may damage and prematurely age the leather.

Customer Reviews



Very comfortable , great as I suffer from Plantar Fascitis especially in the summer months if I wear regular flip flops so very pleased..

Aileen’s fav*


Never had them off. Love the foot support. First time I’ve purchased them online as I normally buy them when I’m in Florida.



Bought a few weeks ago after really suffering for a few months, and after plenty of research. Definitely helped initially as the support and comfort of the heel underfoot area was so sore, I wear them all the time from getting out of bed in the morning, but not for long walks (probably need some Vionic trainers, but wanted to test these out first). I think slowly they might be easing my symptoms, most days I don't need painkillers or ibuprofel gel. It's definitely not getting any worse, I think it's getting better, can't guarantee its the flipflops, it might be a coincidence that it was getting better on its own anyway, but they are helping day to day for sure. These are comfortable enough that I could do a 3 mile walk in them easily and still wear them all day long afterwards.

Style wise, they look less frumpy in real life than they do on the picture.

Downsides: one toe post was really tight, tighter than the right foot, and gave me blisters for a couple of weeks, had to wear a bandaid. And the leather uppers were too tight for the first week or so too, but as they're leather I hoped they'd give, they did and now fit perfectly.

Hope this is helpful for people with foot pain :)



Great shoes. Perfect if you have plantar fasciitis. Highly recommended.



This is my third pair of these flip flops over the last 3 years and because I suffer with plantar fasciitis they are the only ones that I can wear comfortably and actually give relief from pain. They hold my arches and heels securely with support and enough cushioning. I have also stopped getting cracks in the hard skin of my heels since wearing these.
I wear them continuously all summer and indoors thru the winter.
