I think I am going to buy some in-line skates
It's actually a pretty good idea
It’s the hi-lo chassis and the boot being built like an ice hockey skate is the major difference. I use Mission In-line skates, Bauer bought them a few years ago. They are the same boot as the Bauer Supreme that I use in my ice league. Vapor (ice and in-line) are more for players with narrow feet and high arch. Bauer Supreme ice/Mission Inhaler in-line are built for players with wider, flatter feet.I got them. I wear Vapors on the ice, so I figured getting the bottom of the line Vapor in-line skate would be a safe bet in terms of the boot fit, and I was right. They are fantastic really, and for what I want (skating to get some exercise out on an old abandoned tennis court) they are great. I just got back actually and I think they are going to do the trick in term of maintaining some skating feel for this long spring of no ice.
Edit: this is probably obvious to people who think about such things, but hockey in-line skates are a million times better for playing hockey than what I remember from rollerblades. And, in retrospect, most in-line skates must be designed for going straight with stability, not cutting and turning like a hockey player. These Bauers are just better in that regard. Maybe the wheels are closer together or more under the toe?
