Been searching for a good trainer for years now. Was committed to Asics 2120s, wish they still made them. 2130s destroyed my ankle (the lower inside bone is still bigger and really restricts what shoes I can wear now). So in order to keep running I switched to DS trainers (didn't bother the ankle), but after rocking high mileage in that I screwed up my achilles. Long story short I've been running in Vomeros since early 2009. Had some bad knee pain training for my last marathon. So when I started up again I just bought 2160s to try them out but their stiff as hell. Any suggestions on a good high mileage type shoe that isn't quite as heavy as the Vomero and more flexible than the 2160? I understand I've been all over the place as far as neutral/stability, etc.
