Heh.
I did the treadmill, video analysis and all, but I just couldn't get on with the shoes. They were not even comfortable for walking. I was quite upset, having spent out when I'm very cash-strapped.
As I have had no niggles or injury woes with the cheapos, and have done quite a lot of miles in them, I'm not too concerned, but I know they are beginning to wear out now, so I'll have to rethink quite soon.
I'm wondering if I try out the Sauconys again when the weather is a bit cooler, my feet will be less sweaty and blister-prone, and maybe I'll have broken them in by the time it warms up again.
