Find that the muscle feels very weak in the push off. If I stop and try to rotate the ankle I get a kind of spasming shakes type phenomenon in the foot.
First experienced it after running for a train in my work shoes... Also not sure if it relates to a new pair of running shoes I have recently started using...
These are, however my 11th pair of Kayanos and I've never had this problem before.
Am I best to try and run through it to re-strengthen the leg or cancel my plans for a 20 miler on Sunday and swim / bike / total rest instead?
Advice much appreciated.
