I'm pretty much an Ecco guy now. Maybe not the most comfortable, but they last. The soles and uppers are melded together to form one peice during production so the sole won't come apart. Don't know if it's the heat here in Florida, but the glued soles always come apart after awhile.
There's an Ecco outlet store within reach of me now so I should be all set. Have several pairs which I picked up for as low as $59.99. I walk three days a week and find they're comfortable enough.
