The Giro Latch MTB all-mountain shoe ($150) promises increased pedal contact and better grip, which should improve stability and comfort.

The Giro Latch features a breathable, microfiber upper, a hydrophobic interior to promote efficient drying, and also has few seams.

“Latch is a culmination of years of R&D to develop the absolute best flat pedal shoe on the market,” said Giro Footwear product manager Peter Curran. “We wanted to make an all-mountain shoe that would absolutely excel on the descents, while still performing on the climbs and being comfortable enough for long days on the trail. With Latch, riders get a shoe that does just that while also being durable, lightweight, and breathable.”

A size 43 shoe weighs a claimed 334g.

The Latch will be available in four color combinations: black/dark shadow, dark shadow, trail green, and black spark for men’s sizes 39-50. The women’s Giro Latch will be available in three colorways for sizes 36-43: black, dark shadow/sandstone, and harbor blue/sandstone.

The Giro Latch is available immediately from Giro footwear retailers and from the Giro website.
