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 (6.5mm FeelTrue® sole including 4mm lugs), 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 37.5 is only 232 grams 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

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.

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.

The TerraFlex is our first shoe designed for trails. With a rugged, stitched upper, it’s great for running and hiking.

The Mesa Trail is made more specifically for trail running, with a lightweight breathable mesh upper, extra moisture wicking with the “37.5” lining, and a protective welded covering for the adjustable midfoot and instep straps.

Both shoes have a grippy, lugged, dual-chevron tread, and a 3mm TrailFoam layer (“hiding” in the outsole) for just-right protection and comfort.

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

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

The TerraFlex now runs fairly true to size. We recommend going with your usual athletic shoe size.

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 38 in one brand and a 39 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 women’s 43, you may want to check out the “women’s” TerraFlex. The conversion between men’s and women’s is 1, so a men’s 42.5 is the same as a women’s 41.5.

After you purchase a gift certificate, you’ll be able to enter an email address for the recipient.

You could email it to yourself and forward it at a later time if you like.

You can also take the Gift Certificate code and send it to the recipient.

Naboso sock products only qualify for return if they are new and unworn.

Best shoes I ever had

These fit my slightly wider than average foot so well, it's like they were made for me. And they're the best hiking shoes I ever tried in my life. I like trail hikes, with a variety of rugged terrain, slippery mud and stones, ect.. You got a new regular customer! Just got sandals and one more pair of shoes, cos sale, can't miss out on a good deal with this quality. I'll report back in 8000 km's though, curious if they really last that long! Thanks for making awesome footwear for humans and not for italian mannequins, like other barefoot shoe companies does.. 😄

🙁

It was quite a disappointment 🙁 They don't feel barefoot at all. The sole is too thick. The shoe itself is quite narrow. And pretty plastic.

Finally shoes for my wide feet

For the first time in 6 years I didn't came home from our hiking vacation with tortured feet. 😀 Yes! Ascents were great, I was pleasantly surprised with the grip on dirt, gravel and small rocks, and descents were even better, cause my steps felt more safe and thanks to the wide toebox, my toes and pinky toes had enough space and didn't hit the shoe the whole time. Since we usually don't hike in wet conditions, I can't comment on the grip on wet rocks (as some other reviews have mentioned). I ordered my usual size (38) and it fits perfectly, plus I also have some extra space there in case of swollen feet.

Satisfied with xero shoes

My first shoes from xero - and I was very pleasantly surprised 🙂 (I bought another 3 pairs of different xeros after that..) Good sizing (fits according the chart), thicker and non-slippery sole which is perfect for terrain, enough wide for my leg, very comfortable, never any blister!
