Enjoy secure trail-hugging grip when you’re running and hiking.
Thousands of people 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.
Built with the same DNA as the best-selling Prio, TerraFlex lets your feet move, bend, flex and feel, the way they’re meant to. And 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 that feet are supposed to. Plus, they’re so light, you’ll barely know you have them on. A men’s US 9 is only 275g 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 - the middle section of the heel and instep straps is highly reflective for after dark.
Removable 2mm insole - for a more "barefoot" feeling, you can remove the optional 2mm insole.
Barefoot friendly - wear the TerraFlex with or without socks.
To help reduce the chance of getting an incorrect size, we HIGHLY recommend you follow these instructions.
Step 1 - Measure your foot
- Place a piece of paper against a wall (if you have VERY large feet, use a piece of newspaper).
- Place your foot on the paper, with your heel against the wall.
- Make a mark on the paper at the furthest point away from the wall… this will either be just in front of your big toe or second toe.
- Take a ruler and measure from the edge of the paper to the mark you made.
Here’s a video showing the process...
Step 2 - Check your measurement against the sizing chart
NOTE... - For the most reliable fit, we recommend you use the foot length sizing info in the table below. - The TerraFlex is about half a size (4mm) smaller than the Prio. - If you think you’re "between sizes" we recommend you go up to the larger size. - Our sizing recommendations are based on customer feedback and we provide advice on a best efforts basis, however we cannot 100% guarantee a proper fit.
