Lathrop and Sons Synergy.
I used to buy "support" style insoles because my feet were sore and tired after hard days. Once the Lathrops changed my thinking, and got me in the right boot to support my foot, I realized the insoles were for cushioning, and friction prevention, not changing the fit. The Synergy's make a boot that fits more comfortable during hard use.
Like anything that deals with feet though, opinions will vary widely.
