I don't want to hijack another thread, but wanted to understand the reply that blades should be 1/4" shorter than the sole of the skate please. The majority of blades I've seen are mounted to the very edge of the toe and heel of boots, so pretty much the same length as the sole. Can I ask the pros / cons of blades being the same length vs. slightly shorter than the sole? Also if blades are 1/4" shorter should there be a gap at both the toe and heel, or should the blades be at the edge of one extremity?
