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 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.

I gave away a new pair of shoes after I bought these.

I bought 3 pairs of Merrill’s about 7 years ago because I loved them so much. I had one pair left that was new in box and the shoe has been discontinued. It was almost time for me to begin wearing it. I bought the speed force and immediately gave the shoes to my dad. Then I bought another pair of speed force! I love them!

Perfect for everything!

I have used these shoes to do everything from lifting weights and sprinting to running errands and hiking in the mountains. They have maintained their integrity and I have enjoyed them greatly! Thanks for making such a great shoe!!

Speed Force Retro Blue

A stunning piece of footwear. I can’t stop wearing them. I get stopped very often with “ hey nice shoes!” and I have great pleasure taking them off ******** them up and briefly explaining how the foot, the connection with the earth, should work and how these shoes allow the foot to do that. I use them as a warm up shoe, superb for foot activation, before doing my track sessions. Now a Speed Force with a few spikes underneath would be superb! As an everyday running shoe they do need a bit of transitioning into. I am used to zero drop and bare feet but for the very hard stuff the hard rubber outsole is hard. The insole does give a tease of cushioning. Overall a superb shoe which definitely does allow you to “live feet first”

Near perfect running shoe

This was the shoe I wanted when I bought the Prio a couple years ago. Between your foot and the ground it's great like all the Xero shoes. What sets it apart from the Prio is that there is no unneeded material in the upper and it fits like a glove (while still not being restrictive). Speed Force compared to the Prio... The upper is more snug without being restrictive. It provides forefoot width without excessive vertical play for my foot. With the Prio, I had problems trail running because the vertical play near my toes meant the sole could be hanging lower than my foot risking catching on tree roots, etc. There is none of that with the Speed Force while still providing all the flexibility I expect. One of my early experiences with the Prio was doing a gnarly cross country race in them. They were soaked and *so* heavy and they took 3 days to dry out. (This wasn't just running in this rain -- they were fully submerged multiple times in the race.) The Speed Force with less upper material doesn't get weighed down like the Prio with absorbed water and dries out much quicker. Speed Force compared to other shoes I've used... I had a pair of Mizuno Wave Universe 5, which I quite liked. There is still nothing like them for lack of weight. (The pair weighed less than a single typical "lightweight" shoe.) They still had some drop, but it was tolerable. However, they were narrow to the point of forcing me to be careful even when road running. I always wished that I had uppers like my Mizunos and soles like my Prios. And that's pretty much what the Speed Force gives me! The Xero anchoring system allows them to fit securely without needing to be narrow or tight. One of my past favourites was the New Balance 507RG, a spikeless cross country shoe, which I thought was near perfect. Compared to them, you get flexibility, a better feel for the ground, room for toe splay, at the expense of less rock protection under your foot. I had a pair of New Balance MT101, which I had a cobbler peel off the outsole to the forefoot and grind down the midsole until it was zero-drop before gluing the outsole back on. It was a great shoe once that modification was made. It's upper didn't match the soft comfort of the Speed Force though. It didn't provide the same flexibility as the Speed Force's sole of course, but provided more underfoot rock protection -- at least in the forefoot. The Cons? I don't find the grip to be exceptionally good on wet asphalt/concrete. Not terrible -- just not great. Other than that, I'm just about ready to call them perfect. Summary I love them. When the time comes, the next pair of shoes I buy will probably be another pair of Speed Forces... unless Xero makes something even better!

Spoiled Rotten

This is my first pair of minimalist running shoes. They seem to be perfect! Online I found a lot of debate and anxiety among barefoot runners seeking a good shoe. So happy to find zero issues, 20 miles in. I've been running barefoot for the past 6 months and got these for the cold weather and to expand the landscape where I can run using my whole foot. I do wear Lems minimalist shoes for day-to-day wear, and was very happy to see these had a very similar shape with a wide toe box and much much more durable without being restrictive. Highly likely these will steal me from Lems, looking to Xero for my daily wear too.

These shoes are fantastic

Super comfortable! I've been logging some good runs since i got them a month ago - including a few 30km plus training runs, and I have been amazed at how well my legs and feet recover. Really happy with them, so much so i convinced my wife to get a pair, and she is equally happy with them! Thank you.

Love them they are excellent

Walking running perfect fit! Leave the leases lose. If you have them also nonreflective I would ware them to work! Only minor I had to pay 25 euro’s extra on import duty and handling. So if you have a hub in Europe /Netherlands would be great!
