TerraFlex II - Men - Xero Shoes

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.

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.

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 9.6 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.

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 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.

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.

Best shoe I have ever owned xero shoes

As an owner of four different styles of Xero shoes. I enjoy wearing all of them. Without a doubt the Terra Flex II are the most comfortable Xero shoes I own. ( most recent purchase). I wear them the most. Enjoy the lightness of the shoe. I wear them while walking the dog. They work well on pavement and wooded trails as well. I mostly were Xero shoes. The only other shoe I wear is a high slip on boot for riding my motorcycle. Cannot say enough good things about my Xero shoes.

Great for disc golf.

Bought these for a dedicated disc golf shoe and am not disappointed. I love how the straps lock your foot into the heel which is perfect for a couple descents on some hillier courses. The lugs on the bottom add so much traction as well. These are gonna be my go to over the daylite hikers I had. Now I just need a better mud and waterproof shoe over my goretex salamons that have bad foot room, love that pair but they have some drop and no toe room. Overall great for hiking in sloppier conditions caused by mud and wet grass. Great for my disc golf as well on tee pads.

Great shoes

The TerraFlex is a great “get out in the great outdoors” shoe. They are very comfortable and have good traction. They work great on the golf coarse. I wear both these and Prios (a great shoe for pickleball). I find find these run just a hair smaller than the Prio and had to order a half size larger.

Good tread and comfortable

First pair blew out at the side straps. Replaced no questions asked. Sole is thicker than Mesa 2, but I wish that the shoe had the mesa upper with this sole. All in All a great shoe.

First time purchase, best shoes ever!!!

I love my new Xero shoes. I always liked my mocasins because if how the flatness made my feet feel. Now I have that great feel and wide toe box that I always wanted in a more substantial shoe. These are great for walking the dog around the neighboorhood and in the timber by my house. I doubt I will ever try regular shoes again. I got a pair of Prio's too for when I want more of a sneaker dressier feel, love them too. A fan for life. Thanks Xero Shoes!!

The best!!!

These shoes were comfortable right out of the box when I went for a trail run in them. I ended up exchanging the women's for men's as the women's were too narrow for my wide feet but they look the same.

1st pair of great shoes

This is the first pair of Xero shoes I have warn. I am still in the "break-in" phase of wearing them. So far they are working well. I have had not difficulty getting accustom to the shoes... I hope to take these into the mountains soon.

Great for everything - my go-to shoe!

The Terra Flex (version 1) was my first minimalist shoe, purchased in September 2021. At the time, I was desperate to try anything to relieve foot and lower back pain, and figured with the tread on them, they'd be an easier transition, and I could use them for hiking or yardwork or anything else. Well, my first pair just suffered an untimely death as my dog ate through the upper of one shoe (which is sad, because they have held up really well and I've used them for everything). The soles looked like a "regular" shoe that I'd only had a couple months, in terms of wear, and I've worn these for 20 months - a length of time most other shoes don't even see. I loved the fit, the color, and even as I tried more minimalist shoes, I kept coming back and reaching for these all the time. I bet I'd have gotten 5 years out of them. So, I just got the Terra Flex II as a replacement. And I'm very happy that these do not seem to have changed very much from the original. The upper seems a little more tough, but the design and the fit and the comfort all seem to be about the same. Kind of miss the original color, but if that's the worst thing I can think, then I know I've got another great shoe that will be my go-to for almost everything for a long time to come!
