I went to a foot biomechanics seminar a few nights ago (seminars are $5 a pop from local sports med clinic - major BARGAIN) and i was told not to wear my running shoes for boxing training.

Where I am there's only one brand of mens boxing boots available and I have a woman's narrow feet so they are no better for my boxing than my running shoes.

The podiatrist recommended i buy net ball shoes for boxing and keep my runners just for running. Apparently runners are not made to offer any support for lateral movement.

I don't know but I'd guess there are countless contributing factors to injuries and the wrong shoes might be one for some people in some cases.

(I don't think net ball is a worldwide sport so for those who don't know it's a common, Australian female dominated hard court team game similar but different to basketball)
