Make sure your child wears the type of socks they will be wearing while skating when measuring their foot. If they plan to wear thicker socks while skating, consider sizing up to accommodate them. Once you have purchased the roller skates, have your child try them on and check the fit.

Modern roller derby is an international sport, mostly played by amateurs.

I believe that women primarily compete in roller derbies, but there are a few leagues that have teams with men on their rosters as well. How hard is roller derby?

Derby skates feature low cut boots (like speed and jam skates) but are much more padded than other skates (because derby is a contact sport after all). Derby skates also tend to have a strap to help keep the skater's foot in place better.
