Product Description

“This is the holy grail of barefoot performance training. I feel fast, light, and stronger than ever in the gym, on the track, and everywhere else.”
– Leonard M.

SPEED FORCE II – Speed and Power with Barefoot Feel

If you’re looking for the closest thing to a true barefoot experience, look no further than the Speed Force II – a stylish upgrade to our original Speed Force.

Steven Sashen, our CEO, Co-Founder, and Masters All-American sprinter designed the Speed Force with a former Nike developer. It’s the shoe he trains and races in.

Since we released the original Speed Force, people have worn this ultra lightweight shoe for working out, pickleball, taking a stroll and everything in between.

More Breathable and More Stylish

Speed Force II is our lightest performance shoe, weighing in at 6.5 oz. per shoe (M9). If you take out the removable insole for an even more barefoot feel, the shoe weighs even less!

The biggest change: a new, elegant, super-breathable upper with welded components for extra durability.

A Secure, Barefoot Experience

The iconic, adjustable instep and midfoot straps are not only eye-catching, but functional, giving you a confident, secure feeling for whatever you do in the Speed Force II.

With a flexible 4.5 mm thick FeelTrue™ rubber sole, your brain gets the feedback it needs to help you move effectively, efficiently, and enjoyably.

The dual chevron tread grips the ground and, like all Xero Shoes, Speed Force II is backed with our 5,000 mile sole warranty.

WE MAKE PERFORMANCE 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 Speed Force 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 Live Life Feet First!

Caring for your Xero Shoes

To clean your Xero Shoes, hand wash with warm water, mild soap and allow them to air dry. We do not recommend putting them in the washing machine or dryer.

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.

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

Amazing

Best barefoot shoes I’ve ever owned. These shoes look good and feel great. Plenty of protection on the forefoot. While they are designed for sprinting I wear them for all my runs

Zero fan

I think they run a bit bigger than past zeros. Stiff heal will cause blisters.

Great option

I for the most part, go barefoot everywhere. When I am needing something on my feet, this is a great option along with flip flops. They are comfortable and like being barefoot.
