Learning to Skateboard can be a painful process. Take the pain out of learning by setting your skateboard up with Skater Trainers. Skater Trainers help new and old riders perfect new tricks by giving them the ability to practice tricks on flat ground without having the board slip out from under their feet. Skater Trainers are made of a plastic/rubber material that slide over your skateboard wheels preventing the board from rolling. This is an essential tool for anyone looking to quickly improve their skateboarding.
