I have had the same skates for 15 years. Koho's. I know it's an uncommon skate. (Loved their ice skates with the same boot). Point is they finally broke apart so I tried going to a local store but stock was slim so had to go online. I ordered new CCM Tacks 9370R. Looks great. Feels good. Haven't played in them yet. Point of this post is my old skates had the hi lo set up with bigger wheels on the back and a clear curve that puts your heel an inch higher than your toe. The new CCM's seem to have a mostly flat sole on the boot with all the same size wheels. Will this be a noticeable difference while skating? Should I send them back for a Bauer/Mission skate that uses hi/lo, or will I get used to it after a game or two?
