alright every1 just wondering recently i have started using my tredmill. I run for 30 minutes each time at 5.5 mph. So i am able to last the first 8 minutes than the 9th and 10th minute my achillies start burning up. After i finish those 10 minutes i have to hop off for like a minute to stretch them because idk y they are killing me. After a minute of stretch I hop back on and go for another 10 minutes. Than i have to stop and do the same thing. Finally i suck it up for the last 10 minutes but i dont like having to run like this. I am wearing basketball shoes when I run but when I used to run outside my achillies never hurt even with the bball shoes so idk what it could be
