I walked EVERYWHERE on a recent vacation and these prove to be comfortable all day. I usually wear a 7.5 and I ordered an 8, which fit. They're light weight, easy to slip on, and support my feet wonderfully. They can be hazardous on slippery surfaces so just be mindful. I wore these almost everyday for a 6 week trip so this now my tried and true walking sandal. My lower back usually starts hurting after standing or walking for long periods but rarely experienced this wearing these.
