These shoes rock! On average, I run about 25 miles a week, and have historically had a lot of feet problems--plantar fasciitis and mainly stress fractures. I'm a little bigger than the typical runner (6'1" - 205), so maybe the foot issues should be a cue for me to find a different activity, but I just love running too much to give it up. Ever since I switched to this shoe, though, I have not had any foot issues. The Nike Triax is a very competent equivalent to the Brooks GTS, but what tipped the scales for me to go with the Brooks was the company's "green" credentials. I'm not a lefty, tree-hugger type, but we on the "right" should also do what we can to be good stewards of this majestic world God's entrusted to us.
