I slowly transitioned from my Brooks Adrenaline w/orthodicts into Asics Ultimate 81's. I went from the Brooks w/orthos., to Brooks w/out orthos., to Brooks Burn w/out orthos., to Asics Tiger Paws w/out., to the Ultimate 81's. I run most of my mileage on asphalt/concrete and on crowned roads, so it probably wasn't the best idea to turn to flats, as I'm also bowlegged and overpronate extremely bad. But at first I felt good, I could run for about 3 weeks than all of a sudden either my hip or my knee would be killing me. I ran through the early pains, passing them off as my body taking the training. So I popped anti-inflammatories (Vioxx) and finished out my senior year with a bummed knee and sore hip. I'm pretty set on switching back to my orthodics because I was able to run more consistent weeks and train for a longer period than without them. My question is what is a good lightweight shoe, as I'm only 140 pounds, that would be good with orthodics??
