TerraFlex II – Men

The TerraFlex II fits true to size.

This product is currently out of stock and unavailable.

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 272 grams each for a men’s size 42, 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.

TerraFlex II - Men je veľmi komfortná obuv, ktorá poskytuje chodidlu pocit, že je ako "v bavlnke".. Z môjho pohľadu (mám úzke chodidlo) poskytuje dostatok priestoru pre prsty, svojou ergonómiou umožňuje dobrú aktiváciu chodidlových svalov, zároveň je ale noha pevná a pohyb v teréne je tak bezpečný.. Doslova si ho človek vychutná.. Rovnako dizajn tohto modelu je veľmi pekný. Ja som konkrétne zvolila odtieň "forest" - nádherný. Šitie obuvi je veľmi precízne, s dôrazom na detail. Veľmi oceňujem (z predošlej skúsenosti s iným modelom) reflexné pásiky slúžiace na lepšie uťahovanie topánky na chodidle, je to dobrý nápad.. navyše, vďaka pásikom je obuv pekne viditeľná v tme/šere.. Chválim aj podrážku na tomto modeli. Vďaka nej je dopad na podlahu pre chodidlo tlmený a mäkučký. Celkovo hodnotím tento model ako veľmi vydarený, pohodlný a pekný zároveň. Moja osobná skúsenosť: odkedy používam barefoot obuv (konkrétne 2 ďalšie modely značky Xeroshoes + 1 inú), nemám problém s bolesťami bedrových kĺbov a chodidiel (halux). 😀 😀

Una pena de zapatillas

En apenas un año, la malla de la parte superior se ha roto, se han hecho distintos agujeros. Una lástima porqué son muy cómodas.

Unsafe, low quality, but comfy

The shoe is comfortable and looks good, but I coudn't give more than 1 star for the safety issues, consindering they are marketed as a hiking shoe. On dry surfaces it's fine, but as soon as it rains everyting is super slippery ( concrete, asphalt, rocks ). DON'T WEAR THEM ON RAINY DAYS Also, after 5-6 months both shoes started devleoping holes on the sides at the bottom of the toes, since the fabric is low quality. Not sure if I got a bad batch, since most reviews are positive, but I saw people running into the same issues with this model.
