Pulled out the insoles from my Asolo's for a quick inspection and notice how paper thin they were. The Superfeet seeems pretty pricey but I had some tip money from my pizza route and went for it. WOW! I am absolutely floored by the change. The cup that holds you heel feels so secure and cooshy. The arch is set a bit aft and is a little strange at first, but you realize that it is supporting a section of the instep normally in tension. Bottom line, the dogs are barking anymore after a full day in the boots carrying a load.
