The harder the wheel, the higher the durometer number. Most skates in this review come standard with 78A-durometer wheels. A 74A is supersoft, an 82A rock-solid. Since wheels wear out, heavier skaters should go with a 78A or harder. If possible, head out for a test-spin.
Closure options can make or break a boot's fit.
Laces can keep a boot taut around the top of your foot. Ratcheting buckles provide the necessary leverage to close the upper around your ankle and shin. In any case, don't conclude that a skate is too large before battening down the hatches. Often it needs to be laced up all the way so your heel is properly anchored. Pay attention to any pressure on the bridge of your foot, and be sure you're firmly planted on the footbed.
