Fabric boots are often made from a mix of Nylon or Cordura and suede leather, with a wateproof liner for added protection. They tend to be lighter than leather boots, and can be more comfortable at first. The waterproof liners can be sweaty in hot weather though.
From spring '09 Haglöfs footwear will come with a high spec, mouldable insole as standard. - 3/7/08
