Hi I am a new runner since April and have all of sudden found that my feet are going completely dead and like lead whenever I run for more than 20 minutes. I can't seem to figure out why. It makes it very hard to actually keep running. Does anyone have any suggestions as to why this may be happening and how to stop it?

Are your laces to tight? are your feet dead or numb?

I used to have problems with my feet, so I went to get fitted for running trainers and found that my trainers I was running in was 2 sizes to small! Wasn't expensive I spey 30 pound and well worth it jjb sports

Have you always been able to run more than 20 minutes? Have you changed eating patterns?

no have correct shoes, had a running gate done and bought accordingly.

Am used to running between 40-50 min at a time. Have changed eating patterns.

No laces are as loose as they can be, feet go numb and sometimes goes up as far as the calf muscle.
