Product Description

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!

  1. Best Christmas Gift Ever! 5 Star Review

    Posted by

    I ordered these skates for my husband for Christmas. My payment was delayed for about 3 days because of verification issues so I didn't think they would make it in time for Christmas. Well after the verification was done the skates were at my door in 2 days. They came right before Christmas. My husband said they fit perfect and they're the best roller skates he ever owned. He skates in them everyday!! I'll definitely be shopping here again!!!

    Very pleased with this purchase, the skates look amazing and the sizing was spot on, that was the main thing that concerned me. I haven't had the chance yet to give them a good run but initially I'm very happy. They feel like a solid, well made skate.

    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.

    These skates are awesome!!!! Just the right speed, you can have good control for slow or faster, great for beginners, they feel great on my feet really comfortable. I got the purple wheels, they look just like the picture.. Beautiful color

  8. Good for high volume feet 5 Star Review

    I don’t 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.

  15. Great Freaking Skates! 4 Star Review

    Posted by

    These skates are fast! The wheels are durable, which is surprising because I usually have to change out the stock wheels when I get new skates. The only change I would make is that the boot/shoe material is easily scuffed, so I would use a similar, yet more durable material.

    I just got these! The wheels are awesome! I got the grey ones!
