There are people who swear by sandals for hiking. I know that some people have hiked the length of the PCT (2650 miles) in sandals. These also tend to be the same people who wear sandals every day of their lives. I am the opposite, so I can't make any kind of sensible recommendation on sandals.

Are you a dedicated wearer of sandals already or simply someone who is curious, because you heard or read a sandal-devotee stating their firm conviction that this was the ONLY way to go? Just curious.
