I really like these shoes to the extent that for many walks I prefer them to full walking boots (where the terrain demands more in the way of ankle support/protection, etc.), They are advertised as being waterproof - and they are! Not that I should be surprised but often the "waterproof" tag on some boots seems to be just for decoration.
I have had them for about 18 months and would guess they have done a couple of hundred miles on fairly rough surfaces with no sign of wear. Grip is good as is comfort.
In terms of size, the sizing seems to accurate - I am actually an 8.5 (UK) so had to buy a size 9 but adjusted for this with a orthotic insert which filled the excess volume nicely. (I am flat footed anyway so may have needed an insert anyway although the arch support seems pretty good without.)
Would buy another pair when needed.
