Love these! I've been backpacking in Europe & Asia for 4 months with these as my everywhere shoes, and have only just had to buy new
insoles for them. They've gone up mountains, across rivers, and on 10-hour city walks and not let me down at all. I have very flat feet, and I've found these shoes just right in terms on
arch support for me (I like it on the low side). You will need to replace them & adjust the tounge to work with your foot shape, but otherwise you should be good to go... And go... And keep going!
I also agree with the going up half a size - I wear 8 or 8.5, and definitely needed the 8.5 in these!
