I have to get some boots with at least a 1/2" heel and the heel edge needs to be close to a 90 degree. They can go just above the ankle so I'm thinking 6" will be good enough. They don't have to be steel toed but the toe has to be reinforced with something. No steel shank required. What do you guys like? I've seen some Timberland Pros and some Red Wings that both look like they might work. The damn Red WIngs are overpriced unless they feel like my house slippers.
