@Signorina Rollini I have a skate coach and he keeps telling me this. Hardest thing about learning is this dilemma because my body doesn't know yet what it needs to do so I have to think it through.

Sizing was a big issue when I was attempting to upgrade. I wear a half size, so figuring which way to go was difficult. Also how the hardness/softness of the boot material determines break-in time/fit. I didn't have a skate shop near me so I tried rentals to try to figure out the size I'd need and it didn't work out very well. (For the life of me I don't understand how anyone learns on rentals. It was so discouraging at all 3 rinks I frequent.) In the end I bought half size up and supplemented with insoles(not gel!) and ankle booties- worked out great still over a year later with heavy use- over 10 hours a week. Someone mentioned laces. I've found the wider waxed ones keep the fit better through the whole session- and stay tied longer if you don't double knot.

Skated (terribly) at the Roxy in NYC in the early 80's because I lived across the street. Started back up last year at 62. Now obsessed, 3-4 times a week at the rink. Learning to fall right was the first move I tackled. Working on transitions, manuals and backwards currently.
