Foot sensor technology
The kybun shoe‘s flexible, cushioned trampoline sole allows your feet to feel every detail of the ground, which stimulates the health-promoting receptors in your feet.

Air-cushion sole
The novel kybun sole consists of specially developed multi-component polyurethane (PU), into which many tiny air bubbles have been sealed. This elastic springy air pad enables optimal cushioning.


  1. Heel cushioning

  2. Elastic & springy

  3. Perfect pressure distribution

Nimbus sole

This shoe has a «Nimbus» sole and therefore a higher Rebound-Effect. The «Nimbus» sole is the kybun standard sole since 2016. This type of sole offers maximum effect as well as the ultimate in training performance and absorption. The foot pressure is evenly distributed and the power supply is optimised. The elastic and springy material compensates for poor postures and misalignments and the full-length sole profile with larger contact area to the ground ensures optimal grip on any surface. 

Overview of kybun soles

Foot climate system

The airy honeycomb structure of the kybun shoe creates an air cushion between your foot and the ground. Every step pumps a fifth of the air volume into the foot space to cre­ate a comfortable shoe climate.

Surefooted! Lab tests confirm slip resistance

The slip resistance of the kybun soles is backed up by precision laboratory testing in the USA.

Koryo 12 Black

I recently bought a pair of these shoe's after being so impressed with another pair of shoe that I had purchased, the reason for these shoes were to use as a clog type shoe for indoors as the strap on the back can be removed, I have now used them for three weeks and I cannot praise them highly enough, I used to suffer every day with sharp stabbing pains in my right foot that were debilitating and back spasms but since I have used these shoes indoors and my other KYBUN shoes outdoors I now have no pain at all, I would recommend them to anyone and if anyone is thinking they are too expensive they are but I can assure you they are worth every penny.

Pleasure to wear

Since purchasing my first pair of Kybun shoes was so pleased with them that these one are my third pair. Very friendly, no pressure on me at all.

Walking on Air

This is the second pair of kybun shoes that I have purchased. The first trial pair sensible black and sturdy. As I was so pleased with them I thought I would like a more summery pair, hence the pair I chose above. I can walk pain free for miles in them and they look quite feminine. Nice with jeans or smart trousers.

My new favourite shoes

Excellent. These shoes are amazing, and have put a spring back in my step after suffering with my feet for years. I was so delighted with them, I promptly went back and ordered a pair of sandals. I have wide feet and bought mens' shoes to give me the width I need. With the sandals the customer service guy was really helpful about advising me on styles and their width. Fabulous product and fabulous service- I'm converted to walking on air :)
