until i see something more persuasive, i'm calling it "snake oil." Now, it's a great looking shoe, and it may genuinely be watt saving, but on a roller where the major drag is rolling resistance, I just don't see what can this shoe,
BCSM took the prototype of the final shoe and undertook tests on the all-new chassis. With the shoe optimised with pro foot beds and inserts dedicated to that rider, they found they were 28 seconds faster over a 10km time trial (on a roller set-up in lab conditions) against the previous version - a huge gain.
BCSM also tested the shoes straight out of the box with no optimisation and found over the same course that the rider had a 6.5 watt improvement, with less knee deviation. We can only take them at their word as we’ve yet to try the new shoes. We'll be testing them out over the coming days so we'll report back soon on our initial impression.
