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 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.

Please go to Xero Shoes Return Policy page to learn about our 45-day return policy.

We do! We’ve sold Xero Shoes to people in more than 85 countries around the world.
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.

International delivery can take anywhere from 3 days to 8 weeks depending on how long your order spends in customs at the border.

Please note that some countries do require the payment of import duties for international shipments above a certain value. We advise you to know the import regulations of your country and understand that you will be responsible for payment of any duties and fees imposed by your government at the border.

All packages will be marked as merchandise; as a commercial shipper, we are not able to mark a package as a gift (if you’re giving Xero Shoes as a gift, that’s not the same as us sending a gift).
Also, check our Stores page. There may be a Xero Shoes dealer closer to you.

After you purchase a gift certificate, you’ll be able to enter an email address for the recipient.

You could email it to yourself and forward it at a later time if you like.

You can also take the Gift Certificate code and send it to the recipient.

Favorite shoes for running!

I’m a track athlete, a pole vaulter. I bought these to start out my season jumping in flats vs spikes. My other flats, Nike Pegasus, were too squishy for jumping in, and I felt like they made me run different. I didn’t dorsiflex my feet as much.. I had to really think about it to do it in my pegasus. However, I got these, and they’re so comfy and responsive. They have just the right amount of cushion. The sizing is a little funny. I was sent the wrong size at first, and then got the correct size not long after.. Honestly, they’re still about a half size to big, but I’m making it work. When I get a new pair, I’ll go a half size down from where I am now.

Nice!

Super light shoes. I ordered 1/2 size up per the recommendation and still, my foot had too much volume for comfort in these until I figured out I could use the elastic lock laces and leave them loose, and that would fix it. They’re so comfortable, they feel like slippers, or like having no shoes on at all, and they slip on with these laces. I don’t even run; just got them for kicking around the neighborhood—very pleased with the barefoot feel, except protected and with more traction.

Love but maybe size up?

I really love these shoes, but you might want to buy a half size up if you want real space for your toes to spread and move etc.

So comfy!!

The shoes are so amazing! I told my husband they might be the most comfortable shoes I’ve ever owned. I love super light shoes that feel as close to barefoot as possible when I work out and these are exactly that. I would buy more pairs if they were not out of my size. I hope they restock them soon!

Another great shoe!!!!!

This was my 3rd purchase from Zero and the first for my wife. I already knew what a great experience it was to wear Zero shoes and it was time my wife found out. She loves the shoe and will likely purchase something for next summer. Its a whole new experience when you walk around in Zero footwear, try them out. You won't be disappointed

Speed Force loved by Pinay

I bought the speed force for my girlfriend and she absolutely loves them. She grew up wearing flip flops and hated modern running shoes until she met the Speed Force. It was love at first stride.

Best shoes!

I absolutely love these shoes, they are so lightweight, perfect for my walks and hikes and the occasional run. I feel like I’m not wearing any shoes, yet I feel securely supported in them. Thank you for making the perfect shoes.
