Replying to inline skating

I know that most people think inline skating is gay, but i'm physically unable to skateboard, so this is the next best thing for me for summer. anyways, i bought a pair of Solomon skates that i thought would be good for park shit & stuff but i was an idiot & had no idea what i was buying. I was wondering if anyone knows if i need to buy a whole new pair or is there some way that i can like replace the wheels & shit so that i can use them for grinding. I also might have a pair that is perfect for this kind of stuff & don't know it. i'm really new to this kind of thing so if anyone who knows about this shit can help me out, it'd be appreciated.
