TerraFlex Men's SIZE GUIDE
Note: As of July 30th we changed the sizing for the Men’s Terraflex.

We now recommend ordering your regular size.

(If you previously ordered a 9.5, a 9 should now fit you properly)
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 US orders.
*If you normally buy a Euro, UK or JP Size, check out the handy conversion chart below.
NOTE: The TerraFlex fits like the Prio, and has a wider toe box than conventional men's shoes. If your feet are particularly narrow, consider the Women's TerraFlex. Just make sure to adjust the size by 1.5 (for example, a men's 8 is the same length as a women's 9.5).

Product Description

Enjoy secure trail-gripping comfort when you’re running and hiking

Thousands have taken our Prio running shoe out on the trail, but when you want more grip, more traction, and a bit more protection, you’ll want the TerraFlex.

The NEW TerraFlex is a high-performance, true minimalist trail running and hiking shoe.

Built with the same DNA as our best-selling Prio, TerraFlex lets your feet move, bend, flex and feel, the way they’re meant to.

Then we’ve added a lugged sole for grip, and embedded 3mm of Barefoam™ inside the sole for extra protection and comfort. Plus, a durable Tough Tek toe bumper and more aggressive breathable mesh upper.

Why you’ll love the TerraFlex

  • Natural FIT — A wide toe box lets your toes spread and relax. Plus the “XERO-drop” sole (non-elevated heel and low-to-the-ground) allows for proper posture, balance, and agility
  • Natural MOTION — The TerraFlex is flexible enough to let your feet bend, move, and flex the way, well, that feet are supposed to. Plus, they’re so lightweight, you’ll barely know you have them on. A men’s 9 is only 9.6 ounces each
  • Natural FEEL — The TerraFlex uses our FeelTrue® rubber with a removable 2mm insole, to let you Feel The World®
  • Vegan-friendly materials — No animal products in the TerraFlex
  • Huarache-inspired design — The heel strap is not only eye-catching but functional
  • Adjustable instep strap — The “inverted V” straps aren’t sewn down, so you can use them to lock in your instep while keeping your toes free to move
  • Reflective straps — That middle section of the heel and instep straps are highly reflective for evenings and night
  • Removable 2mm insole — For a more barefoot feeling, you can remove the optional 2mm insole
  • Barefoot friendly — Wear the TerraFlex with or without socks
  • 5,000-mile sole warranty — Like all our FeelTrue® soles, the TerraFlex is backed by our 5,000-mile sole warranty

We do! We’ve sold Xero Shoes to people in more than 85 countries around the world.
We use the US Postal service to send our shipments. The cost to ship will depend on the weight of the package and the delivery speed you select; several options will be provided at checkout.

All domestic shipments come with tracking. Limited tracking is available for some first class international shipments depending on the country, and full tracking is available with all Priority Express and Express International shipments.

Though almost all of our international orders arrive without incident, we strongly advise you to select Priority Express International or Express International if you live in a country with a less reliable postal service, including (but not limited to) India, Brazil, Mexico, South Africa, and Indonesia. We cannot guarantee delivery of packages shipped using First Class International.

International delivery can take anywhere from 3 days to 8 weeks depending on how long your order spends in customs at the border.

Please note that some countries do require the payment of import duties for international shipments above a certain value. We advise you to know the import regulations of your country and understand that you will be responsible for payment of any duties and fees imposed by your government at the border.

All packages will be marked as merchandise; as a commercial shipper, we are not able to mark a package as a gift (if you’re giving Xero Shoes as a gift, that’s not the same as us sending a gift).

Worth Every Penny

I'm already in love with my TerraFlex shoes! I wore them on my usual run route today and they held up great on snow, mud, and asphalt at a variety of inclines. I bought a pair of Prios last last year and it seems like the TerraFlex improved on that shoe in just about every way. I strongly recommend these shoes!

Phenomenal

This is a phenomenally comfortable, rugged, and lightweight shoe. It exudes strength while also allowing your feet to move freely. The bottom treads are strong, rugged, and grippy. Great for hiking, biking, and camping. I don't want to take them off. Well done xero shoes!

Great product!

My husband and I each purchased a pair of the TerraFlex and we absolutely love these shoes. We frequently hike a trail that is very rocky and not very comfortable in our sandals so we were excited to see these on sale. Worth EVERY penny!

Happy Feet!

I am so happy I bought these shoes! I have been wearing another brand barefoot style sneaker, which are great, but there is no tread at all and I always slip and/or my feet get soaked when it's wet outside. I tried Xero's TerraFlex because they looked nice, have a bit of tread, and from what I've been reading online, are a great company. I've been wearing them all weekend and I am thrilled! I am a woman with wide feet so I got the men's shoe and ordered a half size larger as recommended. They fit perfectly! Thank you for making this wonderful shoe!

Yes!

My feet started hurting about 10 years ago, so started trying every shoe on the market that I thought would help. Then when barefoot shoes came out, I did some research and decided to switch. Instant relief. Now 98% of my time I only wear barefoot shoes. I wear them hiking, running, to work, and the gym. When Xero shoes came out I was so in love with my first pair of Hana that I wore them absolutely every where. My feet never felt so good. If you’re thinking about buying them do it! You won’t regret it. You’ll feel more grounded, your feet won’t hurt, and you’ll be wearing some of the best shoes I have ever owned. Oh and they are tough shoes, I have torn through some other brands barefoot shoes, not these. They are made to last. So should you buy yourself a pair? Yes! Yes! Yes!

What I always wanted every other trail shoe to be.

These are what I always wanted every other trail shoe to be. The trail shoe trend has been to make them more and more bulky. More padding on the upper. More foam underneath. After my first run in the Terraflex I felt like I was actually ENJOYING MY RUNNING SO MUCH MORE. I love feeling the ground without the fear of anything hurting my foot. These shoes really bite into soft mud and don't slip at all when I'm climbing up a steep incline. They are extremely durable but light and breathable. I forget they are on my feet.

First TerraFlex purchase

I love them like the last 3 pair of Xero shoes I bought. I am on my feet 12 hours a day and Xero shoes treat my feet better than any shoes I have ever owned. I am all done with "shoes that provide great support" as they bend my feet to fit them. I'll be buying Xero shoes the rest of my life.

Great shoes..Really just push the button

They are the best shoes I've purchased in a long time. Very comfortable, great fit and they look good. Size 14 is right on the money for a guy who wears 13 13.5 wide.The community's advise is sound, thank you, and was a real help in helping me to decide to give these a try without bieng able to try them on. You Have a happy customer and possibly a few more. My friends have been asking me about them and I have passed on where to buy. Thanks again going to give the Coltons a try next. Keep up the good work.

Feeling no pain while gripping mother Earth

As soon as I received my new TerraFlex shoes they became my favorite new way to feel the floor. The combination of wide soft inner sole and low-profile knobby bottom really make for a new experience between my feet and the ground.
