The most minimal shoe Merrell makes. Zero drop and almost nothing underfoot, so there is very little between your foot and the ground.
Breathable upper, a wide toe box, and a thin Vibram outsole for grip and abrasion resistance.
For experienced barefoot runners, and excellent as a gym, lifting and warm-up shoe. If you have never run in a zero drop shoe, start with the Trail Glove 8 instead.
