The BOB Ice Skates are the perfect way to get the youngsters on the ice safely and fun. The double runner set up is ideal for any youth who has never been on the ice because it allows for a much more stable stance. The double strap system allows these skates to put strapped on directly to shoes so it takes seconds to put on and take off. The platform on which the shoe rests on is 6" when fully collapsed and 7.75" when fully extended.
