Foot Out, Flat Out—the redesigned 2FO Flat 2.0 was made to get you from the top of the run to the bottom as comfortably and efficiently as possible. Its outsole features our SlipNot™ 2.0 rubber compound, which was developed as a system to create the best pedal connection possible.
Contrary to popular belief, pedal connection isn’t just about rubber—the rubber hardness, stickiness, lug pattern, midsole thickness, and density all contribute to this connection. Specialized's sole construction, informed by a pressure mapping study, led them to use softer foam in the forefoot with firm-over-soft foam in the rear, giving incredible pin penetration, while also reducing the “standing on a marshmallow” feeling that causes foot cramps on long downhills. Along with the new sole, they've also implemented a toe bumper and a captured foam layer, providing protection from rocks and roots when the trail gets gnarly.
Body Geometry sole construction and footbeds are ergonomically designed and scientifically tested to boost power, increase efficiency, and reduce chance of injury by optimizing hip, knee, and foot alignment.
SlipNot™ 2.0 rubber compound is our softest, grippiest rubber, and it's optimized for the ultimate in pedal connection.
