I have a pair of Merrell Chameleon goretex boots, which after much perseverance, I'm relegating to gardening boots as I've also become totally fed up of slipping over in them. Basically, the Vibram sole is simply not aggressive enough for use in mud or on wet ground. Also, the compound is very hard, so grip on rock, even dry rock, isn't exactly that good either.
I recently spent an interesting few minutes looking at the soles of a range of brands of walking boots in Sports Direct - Karrimor, Brasher, Merrell, Salomon, Hi-Tec, Meindl, Asolo and Scarpa. IMHO, all the Merrell boots had cr@p soles in comparison to the others - because of grip pattern, rounded edges and shallowness of grip, despite all having Vibram soles. I wonder if they're primarily designed for use on sand or gravel soils in North America?
From my very brief and subjective examination, I thought that the Brasher boots they had on display seemed to have the best soles for mud and wet grass, followed by Karrimor, Scarpa and Asolo in no particular order. However, I have no idea which brand/ model would be the most fit-for-purpose as a lightweight walking boot though.
