Lately, about 30 minutes into a cardio routine my toes on my left foot go numb. Sometimes on my right, also. It's weird because I will change shoes, and it will get better for a few weeks, then all of a sudden start up again. When I stop exercising and cool down, feeling comes back and numbness goes away. It's always about 30 minutes into a workout, I can set a clock by it. Has anyone heard of this or had this happen to them?
TIA!
