As a rollerblader, these Emporio Armani Skorpion Quadline Roller-Skates are very appealing to me. IThe Armani ones are a little pricey at about $425USD. I checked out the other types from Skorpion, the company who created the skates for Emporio Armani. The Quadline is the much cheaper option with black costing $189USD and colours costing $250USD.
I have no idea where you can buy these in Canada right now, but I will update this post once I find out. You can get them online at skates.com though.
