  • The upper unit utilizes knitted wool to ensure a hug that is akin to wearing a sock. A unique lacing system that involves a cord-and-lock arrangement and intersecting fabric cords on the midfoot contribute to a locked-in fit.
  • A 2-millimeter layer of foam and a footbed serves as the cushioning system of the Merrell Trail Glove 4 Knit Wool. Such a thin profile encourages a barefoot feel. A mildly aggressive outsole offers grip over the unpredictable terrains.

The knit wool version of the Merrell Trail Glove 4 has a standard running shoe length. Consumers can use their usual choices of size when it comes to getting a pair. When it comes to width, the available options are D – Medium for men and B – Medium for women. The foot-shaped curve of this product accommodates the natural outline of the human foot.

Vibram® TC5+ is the compound used for the outsole unit of the Merrell Trail Glove 4 Knit Wool. This full-length layer is tasked with protecting the rest of the platform from wear-and-tear. It has a mildly protruding patterns that are meant to grip the surfaces.

Cushioning is provided by a 2-millimeter layer of foam. This reedy piece aims to mitigate landing impact while preserving proprioception and manual surface control (via foot movement).

The TrailProtect™ pad is a thin shield that’s sandwiched between the outsole and the midsole. Its goal is to prevent sharp objects from piercing the sole unit and causing injury to the foot.

A footbed is incorporated onto the platform, putting a bit more cushioning for the underside of the foot. It doesn’t hinder flexibility or ground feel.

The upper unit of the Merrell Trail Glove 4 Knit Wool features knitted wool, which is a material that closely resembles the structure of a sock. Its job is to wrap the foot securely while ensuring freedom of movement and breathability.

A cord-and-lock fit adjustment unit is used in this running shoe. The system of reedy strands loop through a cascade of stitched-on fabric strips on the midfoot, aiming to manipulate the tightness or looseness of the coverage to agree with the preferences of the runner.

The edge of the forefoot has a TPU cap. This extra layer is tasked with shielding the toes from debris and abrasive surfaces.

A Hyperlock™ TPU film is placed on the back of the upper. This fused wraparound band helps in securing the heel and keeping in place.
