I will never put any other sole in my boots or running shoes

I am a 35+ old military officer who spends most of his waking hours either boots or running shoes. I bought two pairs of these 5 1/2 years ago right after I joined the military. I have since logged more miles road marching and running in both pairs than I can even recall. Well, I recently bought a pair of boots and after getting awful blisters walking with the factory soles I was desperate. I was also just a few days from attempting a 26.2 mile race through the desert with a 40-lb pack. So I took out my 5 1/2 year old SOLE insoles and threw them in my boots. Why? Because I suspected they would still be up to the challenge ... which they were. I finished the race in just over six hours, finished in the top 20 overall in my division, and had but a few minors blisters. I will never put any other sole in my boots or running shoes.
