Ring and talk to a REAL, HELPFULL, INFORMED sales person!The best service i have had in a LONG time!Went with a pair of Bogs Blaze 1000's RT after a long detailed chat with a member of staff who gave great advice, and importantly knew his product!Great boot, but it is early days.Bogs, on me, come up a touch snug, but they are so warm that thick socks are not needed. ( but I like thick socks, so there! )Highly recommended, I shall be back ( tho not too soon if these boots last longer than the Muck Boots they have replaced! )
