I had a pair of Chameleon 4s that were a tad too big. Unfortunately, like my prior pair of Merrells, the heel top wore away on the inside which tended to produce blisters. After a three miler yesterday and two nasty blisters, I threw the old shoes away. Got the Blaze at Cabela's after seriously considering two other brands. The Blaze's attributes, besides being somewhat lower cut in the heel area kept me with the shoe company I prefer. Had them out this morning for a three miler on pavement (fast walk). Good fit, shoe seems true to size, very comfortable on my feet. The big bonus is that the rear heel area is under where I cut my blisters, so no pain right out of the box! Only one day, but we're off to a good start together. Plus, this is a snazzy looking shoe; good for in-town as well as hiking.
