Skating outdoors is very fun and is great exercise! These skates are just what you need to get out there and skate off the pounds. The outdoor wheels on these roller skates are softer and have more grip than indoor speed wheels, so they will go over small pebbles and bumps easier when skating outdoors. Skating is a great aerobic exercise and you can lose a lot of weight. You can even lose up to 20lbs in just 3 months!
