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 women’s 7 is only 8.2 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

With it’s grippy, lugged soles, the TerraFlex is built for running and hiking on trails.

That’s not to say you can’t walk, stroll, road run, Crossfit and much more… you can.

Put on your TerraFlex and Live Life Feet First!

This is one of my favorite features in the TerraFlex.

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.

Shoe sizing, especially online, is not a perfect process. That’s why we have a free exchange policy.

For EU/UK/JP sizing, there’s a conversion chart at the bottom of the TerraFlex product description.

The TerraFlex runs a bit small. We recommend going up 1/2 size from your usual athletic shoe size.

Also, the TerraFlex is wider than conventional trail 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 TerraFlex, 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 an 8 in one brand and a 9 in another. And then, there’s personal preference: three people with identical feet might think the same shoe fits differently.

If your foot is really narrow and smaller than a men’s 10, you may want to check out the “women’s” TerraFlex. The conversion between men’s and women’s is 1.5, so a women’s 8 is the same as a men’s 6.5.

The TerraFlex are terrific!

The TerraFlex have the same perfect fit as the Prios that I wear all of the time. I appreciate having this option with a slightly thicker and more tread-y sole. Thanks again for yet another pair of perfect shoes!

Excellent traction!

These shoes are awesome. They are very comfortable and super lightweight. I took them out hiking yesterday in the rain. They were gripping everything, even walking down steep, muddy trails covered with wet leaves. The only time I slipped was when I stepped on a smooth wet rock, but really, nothing grips there. I've hiked in many shoes and boots and I can honestly say I've never felt so confident in my footing as I have in these. My husband was wearing his pair and decided to start jumping and sliding to test the shoes and he could not get himself to slide. He calls them the "offroad tires of the shoe world." I also have to say that while they are not waterproof or water resistant, even after walking in the rain and through puddles and running water my feet were still completely dry when I finished hiking. I might have to get myself a second pair!

Awesome

Just got my shoes today and love them! They fit so comfortably right out of the box. The toe box is nice and roomy, so far, there are no irritating little seems on the inside that could cause irritation-smooth as a baby's bottom. I usually wear an 8, but I followed the advice on the Xero website and ordered an 8.5 and it was a good call-fits perfectly. I also have the DayHiker and love that one as well. Great job Xero Shoes!

This is it, the perfect shoe!

I've always been a big fan of Xero Shoes, great product, great shoes and so I was pretty excited about this latest model. I've been exceedingly pleased with the Terraflex shoe, especially for hiking. The Arkansas Ozarks has pretty rocky terrain, and finding a minimal shoe that protects against such a sharp trail can be difficult. Not only did the Terraflex provide just that, it is comfy, great room in the toe-box, and a great amount of adjust ability. One thing I really like about this shoe, is because of how well it can be fitted, this shoe is going to fit a wide foot and a narrow foot both really well! Lastly, this shoe required no break in time. It was flexible, move-able right from the beginning, no awkward stiff phase and more importantly NO blisters or hot spots to try and push through. Put in 5 miles on the trail my 1st day with the Terraflex and I kept forgetting I was in new shoes. Well done Xero Shoes, the Terraflex is a winner in my book! P.S. This is coming from an old soul that hates change or anything new 😉

Second Pair

Love them! It’s like walking barefoot at all times. I tried to go back to some old running shoes and they went into the trash can after about 20 minutes. My feet were suffering from being crammed into them. Especially around the toe area.

Terra-flex women’s shoes

Had a little trouble with sizing; had to exchange twice. But I tested them out on a 2 mile hike and they were great! Very grippy and flexible; nice wide toe box but snug heal. I would definitely recommend these shoes.

I could live in these!

The more I wear these, the better I like them. Unlike most shoes, I can wear these from morning till night without my feet getting sore or tired. I'm going to buy another pair soon.

Surprisingly Sturdy

I received my Terraflexs a couple of days ago and couldn't be happier with them. I use to have boots for hiking but I knew I wanted to try out a trailer runner, but my biggest concern with Xero shoes was that I didn't think it would be sturdy enough. However, that couldn't be further from the truth. They have excellent grip to them and just enough material on the bottom to make it a hardy shoe while still being flexible. I would make sure you size up for hiking shoes to make sure you have enough room! I wear W8 Z-Treks and W9 Lena's but I sized up to a W9.5 for the Terraflex and they fit perfectly with just enough gapping in the toe!
