I bought my first pair of rollerblades several weeks ago and now I'm hooked! I am still learning how to use them properly but I am slowly getting the hang of them. The only problem I've had so far is that I keep getting blisters on the instep of my feet (left more so than the right) so I can only wear them for about 30 mins at a time. I'm not sure if it's an issue with them not fitting properly, that they still need to be 'broken in', or that I'm just not wearing the proper socks with them.
I think that they're a great form of exercise and after only a few minutes using them, can feel it in my hips and legs. I believe it has to do with the pushing motion... it's supposed to be really good for toning your butt and legs! Fingers crossed, I can use all the help I can get!
