Great running shoes for longer distances. They provide a good amount of support and cushioning, but they are also more flexible than say the trance 10's making the GTS's better for the slight overpronator and the trance 10's better for the slight to moderate overpronator. They are very comfortable and feel like they are made very well (as all Brook's shoes have to me), but if you are a moderate pronator, I'd suggest the Trance line. If you are a regular (flat footed)runner or a very slight overpronator, then go for these!

Overall, excellent running shoes!
