From our experience we have seen that new shoes can make or break the performance of a cyclist. To this extend that at Bioracer Motion we always mention that a bikefit is specific for a certain configuration (Bike, shoes, pedals, saddle), if any of those is changed, you are strongly advised to get refitted. Raymond, co-founder of Bioracer Motion, has done over 10,000 bikefits and he noticed that different shoes have different "hielsprong". This is defined as the extent to which the shoe it tilted upwards at the heel relative to the cleat, when the cleat is placed horizontally. This case study will address the issue by measuring the differences and comparing shoes to each other both on a inter and intra manufacturer level.
Yesterday a 60+ cyclist came to our Bioracer Service Center to get help for his saddle pain. After cycling for over 14 years (three times a week) without any problems, he started to develop saddle pain on the left side of his bottom. As the pain deteriorated over time, about nine months ago he sought medical help and a haematoma on his left Ischium was diagnosed. Although he received cortisone injection, the problem did not resolve, leading to complete cessation of his cycling activity.
