Kalso Negative Heel Technology

Inspired by yoga and deeply rooted in the belief that wellness should be part of everyday living. Our negative heel sole designs are still inspired by the mountain pose, just as originally created by Danish yoga instructor, Anne Kalsø, in the 1970's.

Please Please Bring These Shoes Back

These shoes were fantastic. Absolutely loved the negative heel and how these shoes made my body feel. I am so bummed not being able to buy them any more. Please bring them back.

The vegan shoe was the big draw for me. The negative heel was a big plus. These options need to come back.

Negative Heel

I got several pairs of Earth Shoes with the negative heel and they are wonderful for your feet and posture. I can't believe Earth seems to be phasing them out. To me, that was their signature distinction as a company. I can find plenty of other styles and brands, but Earth was the only one with the negative heel.

Will you be bringing any of the Kalso negative heel technology athletic shoes back? They really are comfortable shoes. I really wanted a pair of the Kalso Earth Prosper, but there is none in my size.

You’ll also hear from us via email and social media as we near the actual availability date. Stay tuned!

If the re-launch of this brand goes well, new styles will be introduced at a later date which could include more athletic shoes.

I have Kalso solar in a 6.5, I usually wear 7 but your 7 was way too big and had to be returned. Is the sizing for the Prospers similar? It is a final sale, so I won't be able to return these if they are the wrong size, so I want to make sure I get the right one!

Hi, thank you for reaching out to us. The sizing will most likely be similar, as they are both Kalso styles and feature the negative heel. This style although it does say Final Sale- this is referring to the price being the lowest it will be. As always, you may still return this style if it does not work out, please find our full return policyhere. I hope this helps!
