Im 24 and started medium distance running about 5 months ago. About 10km per day. Anyway around 2 months ago my right foot started going numb almost every time I went running. So i went and saw a guy about it and he said that all the muscles in the back of my legs, expecially right at the top underneath the bum, were far to tight. So now before i run, and most importantly after i run, I do that stretch (amongst others) where i bend over, keeping my legs straight and attempt to touch my tose with my hands. At first I found it incredibly hard because all my back leg muscles had become so tight, but over time I can how stretch down far enough to put my hand under my toes. I hold this each time for 3 minutes. Your legs muscles may start contracting but I was told this was good, and as long as its not too painful try keep the stretch for as long as you can (well for the full 3 minutes).. Anyway this has totally fixed that numbness in my foot. I really recommend it to anyone. Proper strething really is the key i've found.
Anyway I hope this helps anyone with the problem, I know how frustrating it can be
