Product Description

“The TerraFlex II is sturdy and protective against outdoor terrain. I really like it for running sprints and up hills and dirt trails. It’s a really great outdoor shoe.” – Chase B.

The TerraFlex II is an update to the best-selling original featuring a more abrasion and water-resistant upper — with no sacrifices to any of the trail-gripping traction, secure fit, and all-day comfort that people loved about the TerraFlex.

TerraFlex II - Lightweight, barefoot-friendly, minimalist trail shoe. NEW for 2022

FEEL CONNECTED TO YOUR WORLD WHEN YOU RUN OR HIKE IN THE TERRAFLEX II

SECURE, TRAIL-GRIPPING COMFORT.

Whether you’re running, hiking, or simply taking a casual stroll off the beaten path, the TerraFlex II helps you feel more connected to the ground beneath your feet.

The rugged 6.5mm FeelTrue® sole, including 4mm lugs for confident traction, provides the perfect combination of protection and ground feel for any off-road activity. The embedded 3mm layer of TrailFoam™ provides added comfort and protection and the toe bumper helps guard against unexpected bumps you encounter along your way. 

Finally, our huarache-inspired heel cinch and mid-foot webbing remain fully adjustable, giving you a secure and stable fit throughout your adventure, while the iconic wider toe box lets your toes splay and flex to empower your stride.

LIGHTWEIGHT PROTECTION THAT FEELS JUST RIGHT.

At just 8.9 oz each for a men’s size 9, the TerraFlex II is even lighter than the original, placing it just between our ultra-lightweight Mesa Trail running shoe and the multi-purpose DayLite Hiker Fusion boot. This is one hiking shoe that won’t slow you down, keeping you going from trailhead to summit.

WE MAKE HIKING SHOES SO COMFORTABLE, YOU’LL FORGET THEY’RE EVEN ON.

If your feet don’t feel as good at the end of the day as they did in the beginning, you haven’t tried the TerraFlex II.
 
Life-changing comfort and superior performance come from letting your feet do what’s natural – bend, move, flex and feel.
 
All Xero Shoes feature a wider, foot-shaped toe box that lets your toes spread and relax, a non-elevated “zero drop” heel for proper posture, low-to-the-ground design for perfect balance and agility, and a flexible sole that gives you “just right” protection so you can bend, move, flex, and safely Feel the World® in total comfort.

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!

Category: 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.

Categories: Mesa Trail, TerraFlex

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 a free exchange policy.

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

TerraFlex 11

The shoes are fine, the only thing that could be improved is the heel of the outer sole, the space between the ridges are too small and they pick up small pebbles which remain on the shoe and track into the house after a walk. If the spaces between the ridges were wider they wouldn't pick up stones. Otherwise the shoes are fine.

Felt great right out of the box!

I’ve never ran in barefoot shoes before, but after using these, I’ll never go back!

Changed my life!

I started wearing Xero shoes because my previous shoes caused my feet to hurt after walking for any length of time. After wearing Xero shoes I noticed the absence of any more pain even after walking in excess of 10 miles on my treadmill. I am 71 years of age, Xero shoes have restored my balance better than when I was in my 40's. Xero shoes are the only shoes I wear.

Absolutely Amazing

I've always wore zero drop shoes but grew dissatisfied with my favorite brand. After reading about Xero shoes I decided to take a chance and I'm glad I did. I was instantly in love with Xero shoes as soon as I slipped my feet into them. They are simply amazing and feel exactly as described on the Xero website. I've put these shoes through the test over the past two months. The traction on muddy trails both flat and on steep accents and descents is amazing. I've hiked heavily rocky trails and not one ankle roll due to the shoes conforming to the terrain. I've hiked heavily rooted trails and my toes were well protected after hitting a root or two. I've ran the trails in these shoes and wished I had discovered Xero shoes sooner. If you're wondering if you should get your first pair of Xero shoes, stop wondering and get yourself a pair, you won't be disappointed.

Love the shoes but….

The webbing is pulling apart on the toe box. Other than that they are holding up great. Love the ground even more haha. Brian

Great for Rocky Terrain

I love minimalist shoes. I wear them all the time, but sometimes the trails get too rocky. If you use regular minimalist shoes you can maybe manage, but you aren't going to be looking up often. These shoes have a great toe box and natural footshape. The rubber isn't padded so it still flexes pretty well but the rubber eats up the rocks that usually destroy my feet. There is even a toe protection area that came in handy when I accidentally kicked one of the rocks. Honestly, these are now my go toe minimalist rocky trail shoes. They are perfect.

Happy feet

I'm on my feet nonstop working 13 hour shifts. These shoes have been more comfortable than even my most broken in footwear. I love 'em!

Solid shoes

I should've been a bit quicker on the return because this pair is about a half size too big but I decided to wear them anyway. I grew up wrestling and these shoes are like a wrestling shoe in that they're light and grippy but I get grip on everything at every angle. So far the best shoes I've ever worn

TerraFlex II - Men

Of the Xero Shoes that I have, the TerraFlex II has the most tread (I'm not counting the special-purpose Aqua X Sport - It has not yet been warm enough to wear those). ++ points for the reflective stripe on the heel-cinch & mid-foot webbing ++ PLUS points for having a pull-loop in the heel to help getting the shoes on -- MINUS points because I have wide feet and with medium-thickness socks the shoe laces are very short -- MINUS points for careful construction / esthetics. The gray & black diamond waffle woven fabric is aligned with the toe on one shoe - so on a slant, but aligned with the black faux leather piece that anchors the tongue on the other shoe - so straight. Bothers me.
