These are ok, none of the issues mentioned elsewhere have affected my boots, they have been and remain waterproof after 4 months of twice daily use( I average 14000 steps a day, 5 miles ish). They were a little rigid to start with, giving me a bit of foot cramp occasionally until the soles relaxed and flexed more naturally. This took a couple of weeks. The only slight issue I have is the profile of the soles, in kentish mud (clay and chalk so both sticky and slippery) they don't offer a lot of security and I'm often bracing myself waiting for the dog to pull me off balance! I now walk on the edge of verges where there is some grass or vegetation to get a purchase on when it has been wet.
