I have looked at the Muck website in order to figure out which model of Muck boots I want but from looking at pictures and reading descriptions I have no idea. I live in the Midwest and first off I want a good sole that won't be slick. I have a buddy who has a pair and he slides all over the place when it is wet going up and down muddy hills. I would like to be able to wear them in summer and early fall possibly even in winter. Any advice as to what model or further questions let me know.
