I had an earlier version of this shoe which I use for construction work. I need a shoe with a sole shank that will give support when I'm on a ladder. I'm a 250lb. guy and am hard on my feet and depend on good support from shoes. I've gone through lots of different brands, but I've settled on these Merrell chameleon 5s. They are pretty stiff at first and a little tight to get on. After a week or so of regular use they fit like a dream. They give me great support, not too heavy, and wear well. Very happy with them.
