I have been working out in old school Saucony Jazz shoes for a long time. As I recall they were considered a “neutral shoe,” and were the only shoes I could go for long walks, do hiit, and lift weights in without knee pain. Sadly, the new style isn’t working for me, it feels really stiff and makes my feet ache and cramp. I have been to running/excercise stores and queried the google and nothing good has popped up or felt right. Any suggestions?
