Featuring a breathable jacquard upper, the Merrell Women's Rubato Trail Shoes are lightweight and allow air to easily flow through the shoe, dispersing heat and ensuring your feet stay cool on long offroad runs. An internal bootie construction with an external rear strap and traditional lacing system gives a secure lockdown precision fit so you can traverse technical terrain with confidence. At the midsole, FloatPro Foam™ gives a durable lightweight ride while FLEXconnect® dual-directional flex-grooves enhance ground connection. Finally, a Vibram® MegaGrip® outsole with 4mm lugs provides long-lasting wear and high levels of traction across both wet and dry surfaces.
