Well, I opted for a pair of New Balance 1004. They have medium cushion and feel real solid with no rollover, plus they some in wide I like the extra cushion of some of the running shoes, but I think these will do nicely while carrying stones or doing farmer's.
When the guy asked what activities i would use them for, I said Strongman Training. He asked what they were, and answered with "whoah". HEHE, that was kind of fun
I wore Chucks for everything for a long time..and they are NOT good for walking/running type events at all.
I wear New Balance because it is about the only cross trainer that I can get in my size. Lots of Strongmen wear boots for a lot of their events (steel toe for stones) and lots of ankle support.
