Product Description

Want to improve your balance and foot and ankle strength?

YES, YOU DO!

People often ask me what’s the best way to improve foot and ankle strength… and until recently, my answer was simple:

Run barefoot or in Xero Shoes.

And I still believe that.

But, we know that your running can be improved by NOT running and doing some strength work in the gym for your glutes and hamstrings.

Well, you can also “go to the gym” for your foot and ankle with the SlackBlock… and, even more, the SlackBlock can help you improve your balance, which will further improve your performance, in just a few minutes a day.

Even if you’re not a runner, you’ll want stronger feet and ankles and better balance. Otherwise you could be one of the millions of people who have life-threatening and even fatal injuries that could be avoided by better balance and more strength.

How do I use the SlackBlock?

When you get your SlackBlock, you’ll get a link for a video that shows how to use it.

But, in short: you’ll stand on the SlackBlock with one foot for up to 2 minutes (you can start and stop if you lose your balance — and you will — during that time). Then switch feet.

There are 3 positions to do this in — “parallel” (with your foot aligned with the block, “angled”, and “perpendicular”. You can do a 12 minute workout in all 3 positions. You can can also simply use the SlackBlock whenever you get a chance.

We have one in our office that everyone uses every time they walk by it 😉

And then almost everyone in our office bought another for home!

As your balance improves, you can adjust the SlackBlock to become more challenging.

Get the right SlackBlock based on your weight

There are two models of SlackBlock: the 13 inch for people who weigh less than 190 pounds, and the 14 inch for people who weigh more than 190 pounds.

Get your SlackBlock and join us with better balance and stronger feet and ankles.

Do you ship internationally?

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.

How do I send a gift certificate?

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.

What’s your return policy?

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

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.

Great way to gain better balance

Looking at this Slack Block you don't think it'll be challenging but you'd be mistaken. It's perfect for ankle strength and all around balance. I use it to help with balance for inline skating, and bowling. Everyone that has asked about it and tried it enjoyed it. I'm glad I found this.

Simply Amazing

Couldn't recommend this product more. It's helped improve my ankle strength and stability in a drastic way, and I've seen a lot of carryover to my activities (calisthenics, yoga, Kettlebell work, longboarding, drumset...everything). I'm a trainer at YMCA that specializes in postural and corrective exercises, and I have used this product with multiple clients (after teaching them some basic arch strengthening, single leg balance, etc). They have seen drastic improvement in their ankles, which is an area that MUST be addressed when correcting hip/general body function. Love Xero Shoes and Slackblock, and I constantly spread the word to friends, family, trainers, clients. People are generally interested in these products and I'm always getting questions about my Ipari Hanas (Got Prios on the way!). They've even helped me get clients, who are now believers in the abilities of the human body and especially of our feet.

This is Great!!!!

I am very happy with my purchase of Slackblock from Zero Shoes. I am 59 years old and in pretty good shape, and have been practicing now for a few months standing on a stable floor to add strength. Within three days of using Slackblock for one minute on each leg, I can easily tell that my balance and strength has greatly increased. I did not expect such quick results! Plus, it is very lightweigh and easy to take on trips to use when there's an extra minute or two to do a standing exercise. Steve and Lena: thanks for carrying this product, and for promoting minimalist shoes for strong feet and a strong foundation.
