I'm a longtime Asics DSTrainer wearer, now switched to Adidas Tempos bec the new DST's are way too stiff. Looking to rotate something with the Tempos that has the following: lightweight stability, low to ground feel, narrow, esp in heel. I tried a bunch of shoes on today and the NB 870s felt the best, however I have no experience with NB and it doesn't seem like their shoes are as popular as other brands. Any opinions on the 870 or NB shoes in general would be greatly appreciated as I'm very wary about trying new shoe models.
