The unique SOLESTAR KONTROL cycling insoles have been designed for cyclists. The insoles support the rider in maximizing the personal potential.
What makes the SOLESTAR cycling insoles so innovative lies in the patented Stabilizations-Delta: it gives the foot the support it needs during the pressure phase inside the cycling shoe and provides longlasting stability. The foot has a better grip in the shoe, allowing power to be transferred directly to the pedal.
SOLESTAR KONTROL cycling insoles contain a Black Fiber core. The material is stiff and yet lightly flexible, specifically developed for use under high pressure loads.
SOLESTAR KONTROL cycling insoles can be worn in any cycling shoe comfortably without any further customization simply by choosing the right shoe size.
