Order a pair of kybun trial shoes for 2 weeks and experience the unique walk-on-air feeling. Trial shoes are classified as B-goods with a small defect that is often not even visible. They may have been worn before, but in this case are professionally cleaned and disinfected. The purpose of trial shoes is to allow the customer to experience the unique feel and great advantages of a kybun shoe before buying. We charge your payment method with a £20 trial handling charge plus a refundable deposit. At the end of the trial you have 3 options:

  2. Keep the shoes. We retain the handling charge + deposit and the shoes belong to you.

Springy like on a trampoline

The kybun shoe will impress you from the very first step. Just like on a trampoline, it provides you with a relaxing and training effect all in ONE! The elastic springy sole trains and relieves your body at the same time. Put on your kybun shoes and start walking, enjoy the unique feeling and benefit from an integrated training experience.

The elastic springy trampoline effect offers the best quality and healthiest exercise you can find! As with the vital elements in nutrition, the trampoline effect is the primary source of your exercise. Depending on the selected style, the sole has a more intense (higher rebound-effect) or lighter (lower rebound-effect) trampoline effect.

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 unique 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

Made in Italy - Montebelluna

The kybun trial shoe Köniz 20 Grey is produced in our own production facility in Montebelluna near Venice, Italy. We manufacture the Swiss air-cushion shoe and its elastic springy sole largely by hand, using a process that includes up to 40 different steps by a dedicated workforce of skilled shoemakers and kybun's Swiss high-tech sole robot. Both production facilities (Switzerland an northern Italy) follow the exact same manufacturing processes.

Strato sole - Your mini-trampoline

The kybun trial shoe Köniz 20 Grey has a Strato sole and therefore a higher Rebound-Effect. The Strato sole is designed to roll better in the backfoot area than previous kybun soles. 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 full strength of the body is optimised. The elastic and springy material compensates poor postures and misalignments by stretching the posterior muscle chain with each step 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.

No compression. Too heavy.

I bought a pair of the Kybun shoes to see if they could assist in my balance training. In most balance training exercises you are asked to stand on a sponge cushion as this destabilises you slightly and therefore challenges your balance system to work harder. I felt I could use the shoes in my daily walk and get in some balance training at the same time. The trial shoes I got were in perfect condition and after several emails the Kybun team confirmed the shoes had the same 2year conditional guarantee as a “new” pair of non trial shoes. The website claims not only do you have the benefit of a thick sponge sole but it compresses so easily you can still feel the ground. I walk daily in minimalist shoes so I CAN feel the ground so it came as no surprise to me that the Kybun shoe with the thick sponge sole didn’t give me the level of feedback from the ground I was expecting. The graphic on the website showing the shoe compression is a little exaggerated. The other negative aspect of the shoes is their weight. I have hiking boots that are lighter than the Kybun shoe. By coincidence I have a friend with a temporary leg ailment that was making it painful to walk. By chance he’s the same shoe size as me so I lent him the Kybun’s. He felt they helped stabilise him more than his normal shoe and were easier to walk in. His only comment was they were too heavy so much so they were actually tiring him out. In summary the shoes are good in principle but do not compress as advertised and are far too heavy to be practical.
