The Isaac Technical Rainboot from Liewood is a transeasonal rain boot with a removable and washable sock. It's vulcanised so it's extra durable, with a pull string closure on the sock, a slip-resistant and flexible rubber sole and a warm wool mix lining. We recommend going one size up as the sock makes the fit smaller and when you remove the sock you get a larger boot - so you get more wear out of it. Genius.
