A ventilated upper is great for hot summer runs, but when the temperatures drop and the wind picks up, you need the protection offered by the Merrell Men's Mix Master Aeroblock Trail Running Shoe. The closed-cell mesh in this minimalist shoe's Aeroblock upper keeps the wind from whistling straight though your shoe, so you'll still be able to feel your feet after a five miles on a frigid trail.

  • Aeroblock fabric in upper features a close-cell mesh lining that traps heat and protects against wind and weather
  • EZ Clean finish on upper sheds dirt and resists stains
  • TPU overlay ensures a secure fit
  • Air mesh bellowed tongue ventilates as it keeps debris out of the shoe
  • 2mm EVA anatomical footbed adds comfort and shock absorption, and is treated with Aegis antimicrobial solution to keep the funk to a minimum
  • Merrell Float midsole is 10% thinner and 25% lighter to provide better ground feel and control
  • Low-profile 4mm drop in midsole encourages a natural stride
  • Merrell Air Cushion in the heel absorbs shock
  • Flexible forefoot shock absorption pad protects the foot by distributing pressure
  • Merrell Mix sole features sticky rubber and versatile 3.5mm lugs that can handle a variety of surfaces
  • Reflective details enhance your visibility in low light

Great Shoe

  • Familiarity:I've used it several times
  • Fit:True to size

These are a great running shoe and work well on everything from dirt, rock, mud, to pavement.

9000 feet on a day off

Out of the box on the trail

  • Familiarity:I've used it once or twice and have initial impressions

I have maybe 3/4" toe room in these. No sliding inside the shoe so I think it should be ok. I ran about 4 miles on the trail and eventually felt a blister between my big toe and next toe, at which I took my sock off and checked it out. When I got home I had pebbles in my sock?? So not a good first test as there were a few variables.


Perfect Shoe!

    Merrell Shoes are the best shoe quality I have owned. Again with this nesop air of shoes they are perfect for running, walking and biking... I would higher recommend this shoe!


    Comfy, light, weather resistant

      I use this shoe exclusively as an around town,and occasionally wear to work. It is really light, stable, comfortable and weather resistant. The only bad mark I give this shoe is the lack of durability. The top of the achilles arch is beginning to wear through, after 2 months of limited use.


      Excellent minimalist casual shoe

        I've been wearing these around for a casual shoe and they have been great so far for that, fairly minimalist in the sole so you get good ground feel (I was tired of wearing clunky hikers around with extra support). I've been running in my Merrell Trail Gloves still but will switch to these when it get's snowy out. The 'softshell' material on these seems good so far, good mix of breathability/water resistance
