Nike just launched the SFB military boot, a project 4 years in the making led by Nike Innovation Manager Tobie Hatfield. Built for speed, agility, and comfort, the ultra-light SFB's upper is made from a polyester woven shell wrapped in synthetic leather overlays, this means there's no 'break-in' time required (typical with most boots), and it dramatically increases drying time.

The SFB breaks new ground in lightweight athletic boot delivering innovation for athletes in any environment. The SFB, perfect for warm weather conditions, is the lightest, fastest drying, natural motion boot on the planet. It features a Natural Motion Cushioning unit that helps allows for optimal support and speed during heel to toe transfer, translated the boot is made to move and form with the foot's natural motion allowing for quick flexible movement in any direction while drastically reducing the weight of conventional boots. Making it the perfect companion during multi-day backpacking hikes which can be cut short if your boots don't work with your foot.

Offering unparalleled traction, the SFB's outsole is fitted with a directional traction heel sole that utilizes reverse tread bars and a slightly raised heel for better traction going downhill, while the Sticky Rubber forefoot lugs were strategically placed to allow exceptional agility and traction in any terrain. Upping the ante on protection, the SFB's mid-sole comes equipped with puncture and laceration resistant thermoplastic forefoot shield and genuine leather with Kevlar sheath, both placed in the sole of the SFB allowing the boot to form to the foot of its wearer while offering protection from jagged rocky terrain.
