Had time to do some shopping today. One of the first things I wanted to get was a foam roller. After searching online at various sports store sites, it seemed I wouldn't be able to find one in-store in Sweden and would have to try to order one online. Found some random forum however, where it suggested buying a "bÄtfender" as an alternative. Went down to Biltema and bought one for $5.
Also bought a wobble board at stadium...
It turns out that the roller is too soft for the IT band. It works with both legs on it for stretching quads and hamstrings though. Will use my nalgene bottle for my IT until I figure something else out.
