Roller derby skates Sure Grip GT50 50 GT

i'm selling roller skates for derby
Sure Grip GT50
size 37
colour black
with 62 mm marble wheels
bearings ABEC-5

They will be good for beginners in roller derby, suitable for recreational rides as well.

I'm selling them because after couple months of riding they got streched and they're too big for me now (I wear size 36-36,5)You can come and try them out in Rvk 101, if you have any questions send me a pm
