Now Boots and shoes can be a tricky subject on forums and blogs. It's a subject which seems to elicit strong views and opinions, shoes? boots? Leather? Gore-Tex? etc. Any opinion on this subject should come with a clear health warning and disclaimer - My feet are personal, what works for me might be torture for you.
Now I love (and hate, but it's loving first) my Keen Targhee II's. They fit my feet (Size 8 to 8.5 feet, usual shoe/boot size 9, wide fitting) quite perfectly. I can wear them out of the box and do a good (8 miles +) walk without any issues. No breaking in, no hassles. I have worn them on the SWCP where the year before my boots caused me multiple blisters on the same section.
I like them immensely. They just work for me. Just.
