While the all-leather upper of the Bridger gives a nod to classic hikers of yore, there&';s nothing old-fashioned about these stats: a pliable, extra comfortable collar; a lightweight TPU forefoot plate that preserves the shoe&';s integrity; BDry waterproofing; metal hardware and a lightweight, aggressive outsole. Unlike the waffle stompers of our youth, the Bridger&';s leather goodness comes with practically no break-in time.
