Product Description

Our lightest, most minimalist, closest-to-barefoot performance shoe.

 


The comic book character The Flash gets his super speed from the Speed Force. We think this shoe will do the same for you.

While we made Speed Force to be a racing shoe, people are wearing it for MUCH more. Some take it on trails (watch where you put your feet given the feedback you’ll get from the 4.5mm FeelTrue® rubber sole), and others simply wear it all day, every day, because of the sock-like comfort.

 

Speed Force 360°

 




Here’s what you’ll love when you slip on your Speed Force:

  • LIGHTWEIGHT – Men’s 9 is only 5.8 ounces
  • GRIPPY – The tread pattern in the FeelTrue® rubber sole feels super sure-footed
  • “BARE-LY THERE” – the mesh upper with its silky smooth lining gives you a real barefoot-feeling

The other reasons you’ll love the Speed Force are thanks to its Xero Shoes DNA:

  • A wide toe box — lets your toes spread, splay and move naturally
  • Low-to-the-ground design for balance and agility
  • Non-elevated, “zero-drop” heel for proper posture
  • The flexible sole lets your feet bend and move the way they’re supposed to, naturally
  • Removable 2mm insole lets you choose the amount of barefoot feel you want
  • 100% vegan-friendly — no animal products are used in the Speed Force
  • 5,000 mile sole warranty

We can’t wait to hear about the records you break in the Speed Force, and how it helps you Live Life Feet First!

We designed the Speed Force to be a racing shoe. Our lightest, most minimalist, closest-to-barefoot shoe.

What we’ve found, though, is people are wearing it for WAY more than that.

Road running, light trail running, walking, hiking, working out, CrossFit, slacklining… it’s up to you. Once you get them on, I’m sure you’ll do things we never thought of (and we want to see pictures of that!).

Put on your Speed Force and Live Life Feet First!

The Prio is our best-selling “do almost anything” shoe — running, hiking, working out, you name it.
With a durable upper, it provides a bit more protection.

The Speed Force is our lightest, “most barefoot” shoe.
More feedback as you step and a mesh upper that holds like a glove, you get a “barely there” experience.

The HFS is lighter than the Prio, more rugged than the Speed Force.
The HFS’s sole has a new tire tread-inspired sole that’s made to handle roads and have extra traction.
The huarache-inspired midfoot and instep straps are “hiding” behind a protective welded material.
And the lining using “37.5” material, which is designed for extra moisture wicking.

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.

So Wonderful

I love the Xero Speed Force. I wear them all the time, from marathons to the office. My feet are so happy. They’ve expanded a size from not being squeezed/confined any more.

Pure joy!

These are the best feeling barefoot shoes I've ever worn. My feet are happy when I put them them on and they're still happy when I take them off.

The best running shoe you will ever purchase.

Honestly, I love this shoe. This shoe provides an interesting sole that is flexible, form fitting (I have extra wide feet), I can feel the ground so well I forget I have them on sometimes, and to be honest my calves and foot muscles have gotten noticeably larger and stronger with simple jogging. Warning, take it slow if you have weak feet. You need to build up your foot and calf muscles with walking and jogging before running or sprinting. You will be faster once you do, but you will risk hurting yourself if you do not permit recovery and gradually build your strength while wearing barefoot style foot wear. BEFORE BAREFOOT: Before Xero Shoe I was starting to have serious foot and knee problems, specifically Morton's neuroma and knee pain/clicking. The raised heel was making me bend my knees like a weird legged person when I walked because I kept hitting my heel and the shoe's attachment points to the cushioned sole were putting pressure on my foot nerves causing Morton's neuroma. Once you go barefoot you won't want any other style foot wear.

XERO Speed Force shoes

Love XERO shoes. Speed Force are my favorite thus far. Super comfortable. Super lightweight. Easy on and easy off. I can slip them on and off without having to tie and untie the laces. Wish there were more color selections. Like a khaki or light brown so I could wear them to work.

Superb Performance “Barefoot” Shoe

This was not my first Xero shoe, but it’s the one I took seriously. It quickly became my go-to shoe for minimalist, one-bag travel. And the shoe by which I judge all other barefoot efforts. I’ve been walking barefoot all my life, but I had been misled by all the shoes that promised ever better foot health with increasingly ridiculous amounts of “support” between my feet and the world. Granted, there are environments in which being actually barefoot can be dangerous. But Xero shoes seem to do the best job of treading the fine line between minimally necessary protection and actual comfort and foot/leg health. I had been wearing a different brand of shoe for my daily 5-12 mile walk at the recommendation of my podiatrist to help address a significant bunion and hammer toes. Because of the mesh fabric upper, those other shoes were at least less excruciating than traditional walking/jogging shoes. But the Speed Force was a revelation. Save for the occasional small sharp stone or unnoticed acorn, these are simply more comfortable than anything else I have ever worn. Lighter, but they make my legs work harder, and I love it. Initially, my walking mile splits took a 45-second hit. But thanks to the work these make me do, I have long since made that up. And they wear better than the other shoes I was wearing. Perfect for minimalist travel. These can be worn in almost any situation. Throw a pair of barefoot sandals in your pack, and you won’t need anything else. Voila! Extra space in your bag. Twice while flying people complimented the SF. Unnecessary but good. Five stars! Bought a second pair to reserve exclusively for travel. Note to Xero: please make a full blackout version of the Xero without reflective straps. Would be the perfect one-shoe-to-rule-them-all.

Perfect Road Running and Track Shoes

Super light and hugs the mid-foot just right. I’ve done 15+ road mile runs in these and my feet feel great afterward.
