TerraFlex Trail Running and Hiking Shoe - Men's

Q: What do I do with those Straps on the TerraFlex?

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.

Trail-gripping comfort for your off-road adventures

TerraFlex Lightweight Minimalist Trail Shoe - from Xero Shoes

Watch this video on YouTube

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 men’s 42 is only 272 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

Put on your TerraFlex and Live Life Feet First!

What do I do with those Straps on the TerraFlex?

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.

What’s different between TerraFlex and Mesa Trail?

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.

How do I find my TerraFlex size?

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 wide and larger than a women’s 38.5, you may want to check out the “men’s” TerraFlex. The conversion between men’s and women’s is 1, so a women’s 38.5 is the same as a men’s 39.5.

How do I send a gift certificate?

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.

What’s your return policy?

Naboso sock products only qualify for return if they are new and unworn.
Please go to Xero Shoes Return Policy page to learn about our 45-day return policy.

Comfortable but not durable

This shoe even though it proved to be very comfortable, it lacked durability. After 4 months of use one of the side straps that are connected with the laces to toghten up the shoe around the foot was torn. Four months later two more were torn. Also the toe bumper started detouching after 7 months of use. So I think this shoe is not proper for mountain hiking.

Like a globe whith protection!

Allways have problems with my knee in mountain And tried with maximalist shoes and it has been worse. I tested Terraflex and run through the woods and for my surprise, my knee don't hurts and my feet feels relaxed at the end of the day. I had soreness the next day and parts of my legs who never had by the exercise! 🙂
