The Grubs Frostline ticks all the boxes; waterproof, warm, comfortable, with a great tread. It’s easy to see why the Frostline is Grub’s best-selling welly. The boot features a 5mm neoprene lining for those cold days. The neoprene is of the "closed-cell" type so it is 100% waterproof. The boot is incredibly comfortable thanks the mid-sole technology. Finally the tread used on this boot has nice deep lugs, so you won’t slip even in the muddiest of conditions.
