My Experience

The Merrell Mix Master Aeroblock Trail Running Shoes are a good all-around cold & crappy weather shoe for mixed conditions. The Aeroblock fabric in the upper is wind and water resistant, cutting down on the stuff that typically makes your feet cold and uncomfortable. The key word is resistant. If it’s a downpour, your crossing a lot of water, or puddle stomping, your feet will eventually get wet, so keep that in mind. Snow, mud, light rain, and wind are no match for Aeroblock. My feet stayed dry and comfortable in those conditions.

A side benefit of Aeroblock is these types of fabrics help retain heat. A bane in warm and hot weather but a boon in cold weather. While running in the teens with “regular” running socks my feet stayed warm. Even in 30 minute runs in the snow my feet stayed warm.

The Mix Master Aero does feature 4mm drop like a “typical” running shoe and plenty of cushion all around. While I am fully converted to minimalist running I did find the cushion to be nice on rockier trails. My feet didn’t get as fatigued as they usually would.

They feature a good mixed sole for running roads and trails. The 3.5 mm lugs give you enough traction in the dirt and mud. Their round profile provides a smooth feel when running on the road. They also offer plenty of flexibility in the footbed so running on the road doesn’t feel like you have boards under your feet.

My favorite small feature is some reflective details. While they aren’t huge, they help give a little extra visibility while running in low light.

The Good:
