I've heard a lot of great things about the Gel Resolution 2 and per the description, I want to try them for a sore achilles. I'm using Addidas Tirands and they are very durable, but a bit stiff, which I suspect is contributing to my soreness. However, the Resolutions are bit expensive for me as I go through shoes often (toe dragger). Has anyone used the Gel Game 2? If so, how do they compare?
