Mammut Sierra GTX Mens Walking Boot:

The Sierra GTX, formerly Raichle and now Mammut, is a multifunctional hiking boot, suitable for light hiking as well as everyday walks.

This popular boot incorporates a GORE-TEX membrane for a waterproof finish, while the velours leather upper makes the Sierra GTX durable and hardwearing.

A Vibram outsole provides cushioning and grip for extra comfort and protection, while a flexible upper construction to the front and back of the boot ensures support without being too rigid.

The Sierra GTX also comes with an Ortholite footbed, a contoured insole that provides additional support when and where it is needed most.
