Hockey Skate Fit
Yes, It is so important. Why? Your skate will go where your foot goes. You don't want your feet moving around in side the boot of your skate while you are playing hockey. You can seriously damage your foot. You'll have helluva time controlling and balancing yourself too. I myself like to make sure my skates are tight when I'm playing hockey. This helps me control myself and my speed with easy. It helps to be able to control your car right? Same thing with hockey skates. You don't want unresponsive steering. Hockey players need full control in such a fast paced sport.
Hockey Skate Bearings
Ah yes, the skate bearings. This is often an overlooked piece of the hockey equipment puzzle. Why is that? Well, when you first buy a pair of skates you can't see the bearings. They are inside the wheels. Most novice roller hockey players will not even bother to read the box to see what kind of bearings they are getting. They won't care weather they are abec 3, abec 5, abec 7, or abec 9. Hell, they won't even care if it's an abec brand of bearings or bones swiss bearings. I for one do. It's very important to me. Bearings help with the smoothness of skating and they also help with the speed. I have preached this many times before, but you don't want your bearings rattling. If they rattle, get new skate bearings quick. Trust me, you'll end up being a far better hockey player because of it.
So which is the better bearing? Swiss or Abec? I don't know. I've heard Swiss are faster. I've only used Abec bearings however. I've also used them with good results.
The conclusion here is testing. Read the above, purchase your skate and don't overlook the bearings or the fit. You'll decide which hockey equipment is best for you.
