Graham. Are you wearing the right socks, you shouldnt be getting a blister just because your feet are wet.
Ive got a pair of karrimoor socks which give me blisters if my feet get wet so I only wear them in winter as an outer pair.
I mostly use in Bridgedales or X-socks which dont give me blisters whatever.
I do have a tendancy to get wet feet in summer as I wear shorts and boots and the rain can run down my legs in the boots. Wet feet are allways a possibility as all boots have a bloody great hole in them so maybe you should look at your socks.
I must admit I would never buy a pair of modern boots that needed breaking in. I got a pair in Keswick this winter and wore them out on the fells 3 days running no problems so I cant see the need to suffer the breaking in period I went through 20 years ago.
By the way my boots dont have left and right on them but my socks do.
