A Crowd Favorite in Every Way
Feel as awesome as you look with Rock Cosmic Superfly roller skates on your feet!
The GT-50 speed skate boot is a crowd favorite with a plush lining and durable uppers. In addition to lacing, there is a Velcro power strap to ensure proper fit. These boots come in a wider fit than other skates, so if you have narrow feet you may want to size down or wear thick socks.
The oh-so popular Sure-Grip Rock double action plates are made from lightweight nylon. With an adjustable toe stop they will always be right where you need them!
Cosmic SuperFly wheels (62mm, 90A) are made with high quality Grip Rite urethane to give you a long lasting and versatile roll. With Abec 5 bearings, they can withstand all that your indoor skating can throw at them!
SIZING TIP: These boots fit a little wider than comparable boots, providing more space to relax your feet. They are made in Men's sizing (the size that will appear on your boot label) and we list the Ladies' equivalent in parentheses to make sizing easy!

5 So fast!
Posted by Dan on 27th Sep 2020
I got the indoor wheels with mine. I've always used rink speed skates, these roll so much smoother, and they're really comfortable. You barely push and they fly. I now know what speed skates feel like, I'm able to keep up with blade skaters.

5 Good for high volume feet
Posted by NMF on 25th Jan 2018
I donāt have a wide foot, but because of my arch my forefoot has a rise that causes a narrow or regular skate fit too tight. The Rock GT-50 fits without having to compensate width in a longer boot. I replaced the wheels because I prefer a slimmer smaller wheel. I had no foot pain after skating on these for over two hours which was a pleasant surprise. The extra padding throughout the boot make this skate a comfortable skating experience.
