My boyfriend is a master tech in HVAC, almost 30 years in the trade. Every year we buy a new pair of these KEEN slip on work shoe. For a shoe to last a year with the way he treats them; wearing 5-7 days a week for a whole year is amazing. We used to buy cheap because they were just a working shoe, something from Wal-Mart but they fell apart quickly... They also caused him back pain.

It is worth the money for these!

UPDATE: It is January 2015 and we just bought another pair... He really likes these shoes. They're durable, comfortable enough, waterproof and slip resistant. Once or twice the KEENs haven't been available and we had to buy Merrell or Columbia. Those are OK but these are the best. I wish he would buy two at a time to avoid that risk, lol.

2nd UPDATE: It is now January 2017 and we just bought another pair. It's a yearly thing at this point, new pair of KEENs every year. He doesn't want anything else.
