I've recently started running and I'm now training for my 10k race (i've already done a couple of 5k).
I was out training the other day in my new asics Gel 1080's when I started to suffer from awful tightness in my calves which then turned into numbness in my left foot - this felt like I had a stump. I kept wiggling my toes, stretching, running slower but the pain didn't subside until I'd got home, stretched, cooled down although admittedly it didn't take too long.
I'm now worried that this is going to be an ongoing problem. I will try the sponge/insoles at the back of my trainers and loosening my laces.
It's great to have a forum for to share problems like these. Any other advice will be greatly received!
