PowerSk8r Skate Weight (Set of 2) We have one mission: SKATE FASTER IN 90 DAYS OR YOUR MONEY BACK. PowerSk8r Skate Weights have been ergonomically designed to provide a comfortable fit with non-slip foam padding to grip laces for utmost durability and consistent on-skate positioning. We found the toughest hook and loop straps to secure PowerSk8r to your skate and withstand short bursts, fast sprints, quick stops, and the occasional slap-shot to the boot. Training with PowerSk8r is not for the weak or the lazy. In the beginning, you will work harder. You will tire faster. You will sweat more. But in the end, YOU WILL SKATE FASTER. We offer two sizes of PowerSk8r Skate Weights: 0.5 Pound: intended for youth skaters, or players weighing less than 100 Pounds. 1.0 Pound: intended for teen and adult skaters, or player weighing more than 100 Pounds. PowerSk8r Skate Weights are to be worn during on-ice training and practiceevery practice--andtaken off during games. When game day rolls around and you're skating without that extra weight, you will realize an immediate performance boost!
