Bests & Worsts Reviews from Amazon

So I wear a 10.5 and ordered a 10 and a 11. I liked the slightly tighter feel of the 10 rather than the slightly larger feel of the 11...so I will be returning the 11. 10 is not really tight but but in my opinion feels better than the 11. I will be going on vacation and walks on some guided tours and don't want them to feel lose. So far just walking around in them that feels good. UPDATE...Very glad I went with the 10. Walking in rivers and pools, they stay on and are comfortable.
