The Specialized 2FO flat doesn't live up to our expectations
One of the unique features of the Specialized 2FO Flat is the Air Mesh upper, which is designed to shed moisture. It works too. When soaked in water, other shoes almost double in weight, but the Specialized 2FO only increases by around 50 per cent.
Specialized says it developed the sticky SlipNot rubber compound in its tyre lab, so we were expecting it to be Maxxis Super Tacky soft. Unfortunately, the 60A rubber is medium density at best. Harder rubber is more durable, but the grip is far below other flat mountain bike shoes we’ve tested in the past.
The Specialized 2FO Flat is much thicker and stiffer than any other shoe on test, which is good for efficient pedalling, but does reduce sensitivity. It might not be what Specialized intended, but the 2FO Flat really feels like an SPD shoe with a flat sole instead of a cleat on the bottom.
The only positives are that it’s well-cushioned, so is great for scrambling about in rocky terrain, and the hex-style tread provides plenty of traction for slippery run-ups.
