Atom Matrix Outdoor Inline Wheels - High Performance 80mm 85A Skate Wheels for Aggressive Inline Skating, Rollerblading & Urban Riding - Perfect for Street, Park & Fitness Skating

I've been skating 1-mile laps (20 to 30 laps per 3 hour session) at a park near my home for the past 10 years or so, but only recently decided to keep a record of the total distance skated. After the old wheels on my rollerblades wore out, I purchased these Atom Matrix wheels, and kept record of the distance skated. Thus far, I've put 1057 miles on these wheels - and estimate that with periodic rotation, they will last me another 250-500 miles or so. I'm about 180 pounds, skating average intensity/speed of 9 to 11 mph all summer long on hot Florida pavement. In the past, I've worn out wheels from other mfg rated 84-85a durability wheels in just a couple of weeks - long story short, I'm very satisfied with the quality and durability of this product, and would strongly consider using them again in the future.
