Updates to All Out Terra Light

The Merrell All Out Terra Light comes with a pack of decent improvements. The sole of the shoe has the 6mm lugs in its Vibram outsole, and they are designed for better traction and for an excellent grip on trails. Its grip is actually its biggest improvement, making the shoe versatile for mud, wet grounds, loose grounds, and other tough terrains.

The fabric of the shoe is also made more versatile. It has the 3D printed breathable mesh with the Ventilated technology, which makes the shoe cool to the core. The airflow is allowed to go in as the heat comes out, keeping the foot cool and comfortable no matter the weather or temperature is.

Merrell also uses the M-Select Fresh technology in this shoe. This technology eliminates sweating that causes bad odor and bacteria to grow. The microbes break down the perspiration through the natural enzymes.

All Out Terra Light size and fit

The All Out Terra Light has a comfortable fit for standard foot size. The toe box is in the standard width, as well as the medial and heel part of the shoe. The inner feel offers a snug fit experience which is enhanced by the secure lockdown features of the synthetic lacing system.


The outsole of the All Out Terra Light has the Vibram, a rubber compound set in diamond shaped lug pattern for better traction and grip. It keeps the shoe durable and efficient on loose dirt and different trail hazards. It is also a great shoe on snow, mud, and watery grounds.


For the midsole, Merrell utilizes the Uni-Fly Technology, a rigid midsole design to disperse impact through the foot, reducing the pressure from the arch for more protection and comfort. There is also a removable Microfiber Foot bed or insole that is made from antimicrobial materials. For added underfoot protection, Merrel also adds the TrailProtect pad.


The upper of this shoe has the new design of fabrics made with 3D printed breathable mesh featuring the Ventilated technology for a cooler and more comfortable running experience. Its woven fabric makes the shoe an ideal running shoe for trail running, perfect on both cold and hot weather. There are some reflective details added to it for increased visibility when running in dim or low light location. The lacing system is based on the synthetic leather lacing, and it offers a more secure but comfortable fit.
