SOLESTAR Insole Cycling Roadbike

“No compromises” is the perfect description when it comes to the Solestar “BLK Sole”, which we have discovered just last year. The sole is worn by many pro cyclists because of its perfect transmission of power and stability. It was developed for riders with highest demands in material.  

Oliver Eisenbach is the founder of Solestar, he is a sports scientist living in Cologne. During his many years of analyzing the typical cycling motion range and the special anatomy of feet Oliver discovered the great potential of cycling insoles. His products are now patent-registered.

Since 2003 Oliver does experiments on cycling insoles together with cycling pros like Gerald Ciolek, Christian Knees and André Greipel - and he has found a working system which is internationally sold since 2010.

The Solestar insoles are fitted to the foot-specific anatomy, they base on a so-called “stabilization-delta” which stabilizes the mobile foot in itself and they have a core made of carbon which is highly resistant to pressure and strain. These insoles are the hidden power in your overall cycling performance - and by the way, they are completely made in Germany.

PATRICK: “It was in may 2016: Sebastian from a company called Komsport in Cologne (a center for diagnostics, training and motion analysis) was in Munich at my favourite bike shop “bikedress”. As a customer you could do bike fitting with their support. Oliver, the founder of Solestar, is together with Sebastian one of the CEOs of Komsport.

In 2016 I had trained for the “Ötztaler Radmarathon” and I was spending many many hours on the bike. My body had some issues quite frequently, I had pain in different body parts but I thought that was part of the deal - until one day, when I had to lay my bike on the ground to be able to descend the bike after all. I had a big issue with my left knee and my muscles didn’t wanted to do anything anymore.

So I stood at bikedress in my bibs and Sebastian looked and me and my body and said without a blink of an eye: “you have problems with the muscles of your right thigh and with your left knee!” - I was deeply impressed. He was able to see my body problems immediately.

So we did the bike fitting together and the first few rides afterwards I almost felt like speeding up to a pro ;)

My problems were gone like 95% and spending time in the saddle was after 4-5 hours still enjoyable.

Back when we met, Sebastian had already told me about the Solestar insoles, but I had delayed that decision to the future - until I had very profound pain again, just 2 weeks before the race.  

I called him and ordered the insoles due to his recommendation. Unfortunately I hadn’t enough time to let my body adapt to them (which is recommended very much: you have to spend at least 4-5 rides with the insoles in your shoes).  

But then I finished the Ötztaler, 239 km and 5500 meters of height, and the only part of my body which didn’t hurt was my left knee ;) I suppose: thanks to the insoles!

I spend so much “quality time” on my bike and everything that makes this time more enjoyable is worth very much for me. So personally the insoles were one of my best investements - besides some pairs of socks I would never want to miss … ;) “

The “deutsche Sporthochschule Köln” (sports university of Cologne) has scientifically tested the effects of the Solestar insoles: the results show that there is an improvement in cycling performance by 6,9%.

We asked Oliver for an interview with FINGERSCROSSED.


Oliver Elsenbach Solestar CEO


You are a sports scientist and coach of cycling professionals since 2003 in the fields of training, sitting positions and orthopedic insole supply. How did it all came together? What do you find fascinating in these topics?

After my studies of sports science it was more like a happy coincidence which brought me to shoe orthopedics. Very quickly I noticed the importance of orthopedic supply in the sport of cycling - and how creative it could be working with cyclists. I just love this technical connection and the different possibilities you have with each person.

In my work I put the whole body into focus. Even after 13 years of experience it still excites me how we can intervene into the construct of bike/cyclist. Working with professionals can be a bit stressful, but there are so many challenges which make the work to me very special and valuable.

You are a cyclist too, tell us more about your passion! 

The movie ET brought me to cycling - the “Kuwahara” was my first bike. Racing BMX and Freestyle was all I could think of back then. Then I found my way to roadbiking until now, in the city I use my cross-bike.

How important are performance enhancing possibilities through perfect material for yourself?

This comes without saying. In former days I didn’t find material very important - but that changed very quickly. Cycling material is like toys - you want to have and try everything. The big advantage is, it is not as expensive as car racing ;)

Why is working with professionals important for developing products that can and should be used by hobby cyclists?

Me and my best friend founded Solestar at a time when we were sponsoring the Leopard Trek Team. The foundation war a risky story, as we didn’t knew how the soles would also work for the greater masses.

In hindsight it was a very brave move as there were a lot of roadblocks on our way. But great feedback, different needs, changing the shoe supplier during a running season and many many hours of experiments were definitely worth it.

Our main marketing lies in the support of professionals. This is good for our product and image. The better the product, the better it is also for the hobby cyclist.

Concerning the impact of the soles: in which terrain does one feel the difference most?

The more pressure you put on the pedal, the higher the impact. I wouldn’t tell by terrain - even on a more chill tour you should have a good feeling in your shoe. The foot is the most important contact point between cyclist and bike.

Why do soles come into play - do they have to be worn together with good shoes? What is the potential of soles?

The soles have nothing to do with the shoe itself. Of course, the more stiff a shoe is and the greater the fit to your foot the better. But what happens IN the shoe is a totally different thing: the soles normally are just a flat surface, but your foot is a three-dimensional construct which is mobile in every possible direction.

Additionally evolution made the foot for walking, running and standing - not for cycling. So the foot must be stabilized in itself. This is why our soles works on the back and front of the foot, too.

A flat foot can be raised by 4-8mm through our sole - which makes the axis of your whole leg longer and the efficiency is optimized while pedaling. The torsional moment is heightened. And this is just 1 aspect.

Is it important to have an individual fitting additionally?

No, this is not important. Our sole works by stabilizing the foot in the neutral position and holds it there. The core of the sole plays the significant role - but when you feel you need an individual fitting like when you have pathological issues, of course we can support that. We also work with Para-Cyclists - even there we do not have to adjust much.

So different foot types play no role?

No - with our concept they play no role.

There are 3 different types of Solestar core materials: plastic, glass fiber and carbon. Why is it this way and which core is best for which cyclist?

The core has always the same form and there is the rule: the more stiff it is, the better. Carbon is really very hard and holds the foot the best possible way. This is independant of comfort.

Quite in contrary, cycling shoes made of more expensive and stiffer carbon are not the most uncomfortable ones. Carbon is unbelievably expensive and we produce completely in Germany. You would be surprised how much it costs ;) Glass fibre is cheaper. So when you want the best material - like the decision between 105er or Dura Ace - it is you to choose ;)

Thanks for the interview Oliver!
