My husband has really enjoyed these boots...until yesterday when a rain shower that barely soaked the grass had him walking around with a wet left sock.  They've been terrific so far and no obvious physical impairment has been noticed with the left boot.  Now just mysteriously no longer waterproof.  And a nonwaterproof boot is worthless.  They are good enough boots that I can hopefully obtain a replacement pair. Update:  We did receive a replacement pair which disappointed in the same exact fashion.  Both of the shoes on this pair are extremely NOT waterproof.  Again, with a light shower just enough to wet the grass (happens during our drought), both of his feet were soaked all day long.  Hi-Tec has a terrific speech written on the inside of its box, but it is just propaganda apparently.
