Men’s Sizing Tips

We recommend ordering your usual size

Based on statistics from the thousands of pairs of shoes sold across the world, we recommend ordering your usual size.

Free Exchanges!

Figuring out sizing is never easy. That’s why we also have FREE EXCHANGES. Most people find our size recommendation gives them a proper fit, but just in case, we have a free exchange program for all UK orders.

Size Conversion

For Men looking to buy the Women’s version because it is narrower – the conversion rate is 1 times, e.g. a Men’s 7 is a Women’s 8.

Caring for your Xero Shoes

To clean your Xero Shoes, hand wash with warm water, mild soap and allow them to air dry.
We do not recommend putting your Xeros in the washing machine or dryer.



Practically anything. The Prio is our first “performance” shoe.

It’s great for road running, light trail running, walking, hiking, working out, Crossfit, biking, and slacklining… it’s obviously up to you. Once you get them on, I’m sure you’ll do things we never thought of (and we want to see pictures of that!).

Put on your Prio and Live Life Feet First!

I’ll admit, this is one of my favourite things about the Prio.

The huarache-sandal-inspired heel strap can be used to hold your heel and ankle in place. Pull the straps through the ankle holes in the sole, and then lock them in place with the laces.

The instep straps can be used to secure your instep, which can free up your toes and forefoot to relax and function better. Use the laces to tighten or loosen them to your liking.

It’s not. But the breathable mesh upper should help it dry quickly if you get them wet.

Shoe sizing, especially online, is not a perfect process. That’s why we have an exchange policy.
For US/EU sizing, there’s a conversion chart at the bottom of the Prio product description.

The Prio fit true to size. We recommend going with your usual athletic shoe size.

Also, the Prio is wider than conventional running shoes.

Sizing for a shoe is different than a sandal, so if you own one of our sandals, that doesn’t mean you’ll pick the same size in the Prio, so use the measuring info if you can.

Keep in mind, though, that because the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device®, can only approximate your true shoe size. Manufacturers model their shoes on different foot shapes, which is why you might be a 6 in one brand and a 7 in another.

If your foot is really narrow and smaller than a men’s 5.5, you may want to check out the “women’s” Prio. The conversion between men’s and women’s is 1, so a men’s 5.5 is the same as a narrower women’s 6.5.

Love my Xeros but waiting for my size to come in

I ordered a men’s size 8 and they arrived very promptly which I was thrilled about, and I loved them but they were just slightly too small as my toes were at the tip, so I’ve returned them intending to order the next half size up, but sadly it’s out of stock. I’ve set up an alert and hope they’ll be available soon. My previous Xero size 8s were fine and I love them.

Design limitation

These shoes are a lot better than many shoes out there, but they are flawed. The instep curves a little inwards and pushes the big toe out of alignment. Triumph of design over function? - so not quite what is says on the tin...

Best shoes ever

So comfortable, I now resent wearing any other shoes.

Ideal barefoot trainers for tennis.

I have been looking for barefoot shoes that would cope with the demand of playing tennis and have now found them! These shoes are comfortable and sturdy enough to cope with the twists and turns of playing tennis. They look pretty cool too.
