Interesting this as I am tempted to invest in a pair. Did 8 miles this morning over Baildon/Ilkley Moors in the mud, in my Roclite 312's, and was all over the place in the mud ! I've used 312's/320's for the past few years, but having done the FTOP the other week in my 212's have decided that I need more grip & less cushioning. Especially in winter when the ground is soft.
