On Cloudrock Waterproof 2.0 Speed Hiking Boots Blue Indigo Cobalt Mens 12.5 UK 12 EU 47.5 Cloudrock Waterproof 2.0 is an updated version of On's popular original speed hiking boot. It is built for improved traction, pace and protection in less-than-ideal conditions. It features upgraded Missiongrip™ rubber which adds traction, while new forefoot lugs bite into soft trails. The Swiss-engineered FlexLock system means laces can be tied traditionally or with a single pull (and drastically reduces the risk of laces getting caught on the other boot). The top eyelet can actually be used as a traditional eyelet or a speed-hook. The 20% recycled and durable membrane is wind- and waterproof. The high collar fit has been slightly improved, and like the tongue, is reinforced with padding. The rubberized toe mudguard has grown, while still remaining light and flexible.
