Just my experience with Russells.
I wanted a lightweight pair for upland hunting here in the NE, decided on their Woodcock TLC's with a few options, advertised as their lightweight boots. I specifically waited until the 2006 Vintagers to have the company president measure me so there would be no mistakes.
Boots arrived 4 months later and they fit terribly. There were seams on the inside digging into my feet, tight across the front, loose in the heel, my heel was slipping up. I have a $39 pair of boots from Costco, made in China, that fit better.
I called and to their credit they immediately refunded my money, asked me to re-measure my feet and send the boots back which I did.
About a month later I called to find out what was going on and they said they were sending a pair that was similar to what I wanted just to try for size. What arrived was a pair of their High Country Hunter, 12" boots for sheep hunting and such, nothing like what I wanted. I tried them on for fit and called with what I thought needed to be done to get a good fit on the TLC's I wanted. They took the info and I never heard back.
For the record I am a standard 10D in store bought shoes, the boots they made for me were tagged 10.5 and were still tight.
I know that others swear by them but it didn't work out for me. They were courteous, but didn't follow through.
