Are you heavier or have a heavy stride shoes might be done, If they are midline running shoes might be time to replace. I get about 300-350 I am 155lbs. and have a heavier heel strike. I would say ice the shins and later if it make feel good use heat also. I love my heated seats in car after a workout. But I am not hurt and its mainly on my derrier and back of thighs. The heated steering wheel feel terrible on hands after a ride. :)
