I just replaced my 4 year old Vapor boots with the green ones (front one first). The rear one went on last week and has been a bugger to break in. Matt Rini mentioned removing the stiff inner piece and others here mentioned doing that in the new Carbitex boots too.
Problem is the inner piece is stitched in at the bottom. For those who have removed it -did you cut it out? If so did you remove just the ankle portion or the foot sidewall part too? Method?
