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 light weight, 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 an 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 is 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’s has our 5,000 mile sole warranty

FAQS

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.

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 men’s 8 is the same as a women’s 9.5.

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).
Also, check our Stores page. There may be a Xero Shoes dealer closer to you.

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.

Caring for your TerraFlex

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