I go Redwings when I need a boat to last. I wear them to death and I seem to get 10 to 12 years out of them. I started wearing 8" Super Sole boots decades ago when I was roofing. I only have to replace the insoles. I did have the sole of one develope some problems and start to seperate. I learned that particular sole does not like acids and I had not been careful around muriatic acid.
