This men's hiking trainer is designed with plenty of features for practicality and comfort. The GreenStride sole foam is made using an EVA blend including 75% biobased materials derived from sugar cane and responsibly grown rubber. The upper combines Premium Leather with durable ReBOTL fabric containing at least 50% recycled plastic. The upper has also been finished with a special treatment to resist spills, stains, and other common everyday mishaps. With the leather on this hiker, Timberland also supports responsible manufacturing of leather via the Leather Working Group.
