Yes the similarties are amazing rollerblading is basically my summer skiing. The biggest connection is on rails. It also helps your balance out significantly. Honestly i bought 99$ bladerunner Furys and they worked fine however i would recomend Razer street cults.

first, like this response don't let haters get to you. Secondly if you want to get into the sport I would HIGHLY recommend the remedyz os 4's they are 130 for a high quality skate that will last a long time.
blading is fun, makes you realize real fast what a lil bitch sport skiing is (not just cuz itz full of spoiled simps with to much $) but because you have to man up and bust ass for your tricks.
my advice, doesn't really matter what blades you get, just learn to skate be4 you start hitting the park.
AND SKATE FAST, because when i'm out there blading i'm repping you and when your out there you're reppin me so don't be a bitch
heres a lil free rollerblade vid me and my homies made last summer
It's really fun and hitting rails isn't that different but in my opinion it's a lot harder and you need more confidence. Also I have razors genesys 9.1 skates and they are awesome. Check them out on rollerwarehouse.com
