Hi,
I began cross training, mainly the treadmill and bike, I ordered a pair of New Balance, through my gym with discount and I got correctly measured for size and width, they were noticably cheaper than anything else I had seen.

Now I am big, but found them broad and supported my foot , I also noticed that previous calf discomfort dissappeared, so for that reason I find them really comfortable and supporting.

And yes I have shoes that no longer fit I can change approx 1.5 shoe sizes dependant on my weight.

Graeme.
