Bought these for an almost 2 year old.
Pros - adjustable, will fit small shoes fairly easily. Give good stability on the ice.
Cons - don't stay on very well, especially if shoes are small. Buckles on straps broke after a couple of sessions.
Solutions - bought some polypropylene webbing and camlocks online, and made new straps that won't break. Use sticky tape to wrap around the middle of the skate and shoe - fortunately, there's a gap in the middle of the runner that allows this without having the tape dragging on the ice. If you're prepared to spend an extra £5 and do a bit of sewing, plus remember to take some tape with you each time (I use hockey stick tape, but anything will do), then these will allow even a very young child to go on the ice and enjoy themselves. Would have been 4 stars if they had used webbing to begin with, as found on some versions from USA and Canada. These skates may stay on a larger size shoe better, but will probably move on to proper skates by that time...
Summary - will do the job, but not perfect. However, good stability, and easier to balance than a proper skate. If you are prepared to do a little work, they will do the job very nicely. (Lots of retailers sell webbing and buckles. If you don't want to spend ages searching, then google "point north", as they were the cheapest I could find.) But sticky tape also essential!
