Rollerblade Macroblade 110 3WD Men's Inline Skates for Adults - Grey & Yellow Performance Fitness Skates - Perfect for Outdoor Exercise, Fitness Training & Recreational Skating

Absolutely love these blades, but be careful they go fast. I mean, think ski slop fast even on the slightest hill, except when you wipe out you hit blacktop not snow. Stopping and zig zagging needs to be planned before it gets out of control. Then you can barely walk for a week. I guarantee whether from exercising or bruising you will have a swollen body before the end of the day. I love them!!!!
