I have never tried either the dubarry's or the mpx's. Having looked at them, I dont think they would suit me as I have big calfs. I tried gill ones but could barely get them on.
I now have a set of these
yacht bootswhich are great. Really warm and comfy and les than half the price of the others.
I havent worn them for seriously long periods but have worn them for several full days on the water and didnt want to take em off at the end of the day.
