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 – Women’s 7 is only 5.2 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 all-around, do anything shoe. It’s been our best-seller since it came out.

It’s got more durable upper materials and offers a bit more protection.

For people who don’t want as much barefoot feel as the Speed Force gives, the Prio is the perfect solution.

Love!!!

I've worked out in these shoes a few times and love them. No arch cramping or foot pain! I have wide feet with very little arch and ordered my normal cross trainer size and they fit perfectly.

Love my speed force

I am impressed by the speed! I work in them all day ,I’m a practitioner with Advanced Biostructural Correction! So I work on correcting body’s all day and they give me energy and my feet don’t feel tired! They are super lightweight! And propel me forward in in walking! Everyone needs a pare , not just athletes!

Aka running slippers

So comfortable and fits like a sock. The speed force feels like nothing I've worn before, and I've been into minimal / barefoot shoes for eight years now. They are so lightweight and sleek, it still wows me each time I pick them up. My feet are at the wider spectrum, so socks are a must for me... I learned the hard way. I love these shoes 🙂

Best shoe ever!

Except for having to knot the ends of the laces because my feet are so narrow, they are the best shoes! I forget I have them on. I have received compliments for how nice they look. When I got them, I took my Cassie shoes down to the shoe repair shop to have the laces shortened, and until I got them back, I wore the Speed Force from when I got dressed in the morning until I put on PJs at night. I’m still relearning how to run with minimalist shoes, so not getting many miles in yet, but I’m enjoying the process. And they make great CrossFit shoes too!

Love these shoes!

These are my first pair of Xero (or any minimalist) shoes and I love them! As soon as I took my first steps in them, my feet & body said, "Yes!" I'm not an athlete, not a runner - wearing these for long walks on paved, gravel & dirt paths. The website says they fit true to size, and so I ordered my usual 8.5 (and I have a narrow foot). They were way too small. I next ordered both the 9 and the 9.5 to compare and went with the 9.5, although I think the 9 would also have worked. My sister, a size 8, tried both the 8.5 and 9, and went with the 8.5. We're both very happy with our shoes!

My new favorite running/CrossFit shoe!

These are wonderful! They fit true to size (I'm a 10.5) and are so comfortable. I use them mainly for CrossFit, however that means a fair amount of running as our gym programs running into our workouts multiple times a week. I haven't taken them on any long runs (more than a couple of miles) but I expect they would hold up well. They had enough traction to keep me from slipping when running in the rain the other morning, my socks got fairly saturated but no blistering or other issues I've had with past running shoes getting wet. They do well for Olympic lifting too, although if that's the main focus I'll usually switch to a stiffer shoe. The Speed Force is much better for my feet than the Prio, I have narrow heels that tend to slide around in the Prio, but they fit perfectly in the Speed Force.

happy feet, so comfy

My feet are enjoying these shoes... they feel great and are comfortable. I'll be putting them to the test soon at a Spartan Stadion race!

Truly fits like a slipper!

I put these on and right out of the box they felt like wearing slippers! I’ve been looking for something to replace my years old Inov-8 f-lites that aren’t made any more and that I love. I also run in Vibram 5 fingers for shorter runs. I love the Speed Force! They truly have a barefoot feel (ie if you run on small stones you will feel them!) and just feel cozy on my feet. I’m excited to have found a new running shoe. I have the Prio in an 8.5 and found the 7.5 in the Speed Force to fit great. I like the Prio but I love the Speed Force!

Great for weight lifting

I bought this to have a barefoot feel when lifting weights. They have been great so far. I am also getting used to wearing them for cardio.
