Absolutely agree with you about the tread on the sole being too shallow, it's probably going to go bald really fast. Don't know what the hell they were thinking, the grooves should be 2x as deep as they are, maybe they were trying to find a balance between cushion and board feel and decided to go with cushion over making the life span of the sole better. Either way they feel like they will skate well. At least they were only $30.
