I recently bought a second pair of these shoes because the sole was starting to wear out after 4 years of frequent (usually daily) use. I often wear them as my main shoe in warm weather, which is where I live most of the time. I have to say that I usually wore them without socks (I live in warmer areas) which probably accelerated the deterioration/peeling of the sole. The old pair can still be worn, but I put orthotics in and use them for "rougher" work (like going to the gym on a legless day). I love these shoes because they are great for everyday wear (with shorts). or jeans, no socks), but can pass as slightly formal or casual-formal (with pants, with or without socks) when appropriate. I've even worn them with a suit once or twice.
