Yes. I managed it on my recent LEJOG tour during the wettest May in yonks. Wore Northwave Celsuis Goretex boots and Berghaus Paclite jacket and overtrousers. Left loose (ie with no clips or owt) the overtrousers covered the top of the boot and, sorry to contradict anyone, I didn't get wet feet. Actually I did, for the first few days, then I bought the above mentioned boots from
Evans Cycles in Bristol and posted my shoes and neoprene overboots home, cos they didn't work. Rest of trip, loadsa rain, dry feet.
