The Timberland Belknap Mid F/L GTX weighs 1160g (pair, size 11); up to size 14; synthetic upper with Gore-Tex waterproof lining; leather overlays for durability; firm toe box protects feet on rockier ground; reasonably deep lugs for a good grip in mud. But very soft sole flex detracts from performance on rockier ground; upper is quite soft and may not be as durable as all leather.
