A size 10 will need thick socks and not be very happy. You can use my analysis to determine if these are the skates for you.
They will need some work on them to get them in the shape needed to perform. Nothing major just some oil and a wrench. The foam is peeling on the tongue but still cushions. Eventually they will need new wheels and bearings.
