During cycling, a constant plantar flexion movement (pressing the forefoot down and lifting the heel) occurs. During this repetitive motion, the metatarsal heads (the ball of the foot) experience excessive pressure due to the body weight. Supporting the metatarsal heads, which are the most prominent bones at the bottom of the foot, is extremely important during cycling. 

By supporting the feet with Sidas Custom Cycling Insoles, we relieve the pressure on the metatarsals and sesamoid bones. The use of a metatarsal pad and the addition of the right amount of arch support distribute the pressure forces more evenly over a larger surface, significantly reducing concentrated excessive pressure. Additionally, adding calluses during professional bike fitting provides further support for pronation or supination, allowing for more even pressure along the metatarsal heads. When high arch support and a metatarsal pad are combined with a quality insole, no strain is experienced. 

Therefore, with your custom Sidas Cycling Insoles, you will ensure the correct arch height for your feet, protect them with a vibration-absorbing metatarsal pad, and enhance your performance. In addition, the common knee and hip problems caused by cycling will also be prevented.
