White Boot company of Spokane makes the best fit and durability period. I have two different size feet and they custom a fit that is better than any tennis shoe or slipper. Get the Smokejumper with the leather arch, available in rough out for ironworkers, also. Danners feel good but the upside down seam burns out where the White just run off the sparks. Expensive but rebuildable. I've only gone through two pair in 18 years. . .
