I'm a half size, what should I choose?

If you’re a half size, you can size up for a looser fit - or down for a more snug one.

I'm a full size, what should I choose?

Vessis fit true to size! So, go with your most common US sneaker size.

Will my orthotics fit?

Absolutely! We want to make sure as many people as possible can enjoy dry socks, so if you wear orthotics you can swap our insoles for yours. 

Do you have wide sizes? What about narrow sizes?

At this time Vessis only come in standard widths. That said, we find that many wider sizes can find the right fit for them because of our extremely stretchy and adaptable upper knit. For our Weekend collection specifically, that one was designed a little wider to begin with, so you might find it works well for you in your normal size.

If you are a wide women's 7.5 or 8 for example, try the men's 7!

Most narrow style: Cityscape
Most wide style: Weekend

Will you ever make men's sizes larger than 13?

Extended sizing is absolutely something we'd like to offer in the not-so-distant future. While there are no concrete plans at the moment, we're keeping track. Send us a message to letting us know what size you'd like to see.

Will they stretch?

They will! The ankle opening and the upper knit will be snug when you just get your Vessis. With time and use, they'll give enough to create a comfy fit for your feet. While they won't stretch enough that you might need another size, they won't feel tight for long!

How does sizing compare to other brands?

Good question! Vessi sizing is a little different than other brands because of how the upper knit stretches and adapts. There's no other direct equivalent, so we recommend going with your most average sneaker size in your closet. 

Do you have kid's sizes?

We sure do! Check out our brand new kid's collection.

Can I wear a men's/women's size if my normal one isn't in stock?

100%! Our shoes are fully unisex in design, so you can totally switch between men's and women's sizes depending on what's in stock. 

A few things to note:

- Men's sizes run bigger, so size down from your normal women's size if you're doing a women's -> men's swap. 

- Our women's Weekend collection runs big, so size down two from your normal size if doing a women's -> men's swap.

- Men’s sizes are a little wider and longer than women's. A few mm only! Basically the width of an American penny.
