I wore skates a size small for awhile (3c, I was remeasured as a regular 4) and I got cqlluses on my toes from where they crunched into the boot, but it didnt effect my skills. When I was in a regular 3 my feet fell asleep in minutes, and i could barely skate. They only hurt while skating, not off ice. I was so mad at the fitter who threw my $250 down the drain...the skates were awful for me, even if i could get my feet in.
So if they feel okay, on the ice, you should be fine.
