I've had a pair of Keen sandals for years and they've been both very comfortable and very rugged. I needed a new pair of shoes for my new-economy career (insert massive eyeroll here) working part-time in a grocery store. The shoes are solidly built and have a shape & size very similar to my old sandals, which is exactly what I was looking for. They're comfortable enough for long shifts, and they grip well on the hard concrete floors when I have to pull 1000+ lb. pallets around. The wrap-over toe thingy helps to protect the shoes when stocking lower shelves (or when I'm just crawling around on the floor grovelling and what-not). These are solid work shoes which will hopefully outlast me.
