Fully expect this to go cold with it being go outdoors BUT Merrell are a good brand for outdoor footwear and these are half price assuming you have a membership card.
I picked a pair up the other day, yet to use them in anger but they've been worn around the house for a few hours to break in which wasn't needed, comfy straight out of the box!
Can't comment on waterproofing but I assume they will have a decent degree for showers & wet grass. Seem well put together, look great and are VERY light & comfortable.
Not much info on the go outdoors site but the assitsnt was quoting "10,000" HH, I assume she meant 10000 steps / flexions in wet conditions....Happy so far but proof will be in the pudding!
