I wear an 8 regular, but I need a wide toe box, and finding a comfortable shoe that I can wear walking in the hot temps of Southern CA over pebbles/sand/tallus, etc. proved a real challenge. I tried two Salomon Running shoes, Xero 'Minimalist Barefoot' walking shoe, a Merrill boot a few Oboz Sawtooth hikers and through Amazon Wardrobe (love Amazon Wardrobe!!) I tried 5 pairs of KEEN hiking boots.
In the end, I bought the Saloman in 8.5. and love them. They are so well constructed with light fabric, great grips on the bottom that will not let me slip in loose stones, a great arch support, comfort heel, and yessssss...a wide toe box that is perfect. I've never had shoes with the elastic, no-laces, but I keep them fairly loose, and I can wear these with both thin and thick cotton socks. They conformed very quickly to my foot; I wore them about three hours the first time, and they got more comfortable as I wore them. Pricey...but if a shoe that I want to spend a lot of time in gives me a great fit and no blisters, I gladly paid it. These will last a long time. Highly recommended.
