I walked half a day with these shoes, no pain on the first try, so comfort is there. I walked into dry land earth, so on this point no opinion on the seal. By cons, returning were spent under water to remove dust, I'm sure not having poured water in and as soon as I put the faucet above the tip j ' I felt water get where I normally have my toes. I imagine walking in the wet grass give the same result. I have to grease with grease "seal", then we'll see. But there is a label "waterproof" sewn on the shoe, so it should not let a trickle.
I bought 42, shoe size for me and I found that the size was good.
