- The New Balance 852 v2 is a motion-control training shoe that employs a host of technologies to keep the foot supported throughout the workout. It inherits the ROLLBAR technology in the heel and midfoot sections to prevent the foot from overpronating or supinating.
- New to this version is the N2 compound. It is a low-profile cushioning that is durable and reactive to impact.
- New Balance also replaced the outsole in the new iteration of the shoe. This model has a diamond tread pattern and pronounced flex grooves in the forefoot.
The New Balance 857 v2 features a non-marking rubber outsole. This compound is abrasion resistant, grippy, flexible, and it does not leave streaks on floors. It extends partially to the front to serve as protection from abrasion and impact during workouts.
Flex grooves are found in the forefoot area to facilitate proper foot flexion. Diamond treads in the midfoot and heel increase the surface area which inherently enhances the traction of the rubber material.
The New Balance 857 v2 uses a number of technologies for its midsole.
N2 is a low-profile type of cushioning that is durable and responsive to impact. Found in the midfoot section, it enhances the shock absorption in this area to protect the arch.
ENCAP is a dual-density midsole that provides stability and comfort. Polyurethane makes up the outer rim of the midsole. This material is firmer compared to the ethylene-vinyl acetate foam it encompasses. The perimeter of the midsole is less squeezable than the middle area to provide lateral support, while the softer foam in the middle delivers shock absorption.
The back of the foot is kept stable with the ROLLBAR. Embedded between the outsole and the ENCAP, this technology prevents the heel from wobbling during movements. It acts as a stabilizer, circumventing too much rolling in or out while in motion. This feature is commonly used in New Balance walking shoes.
A molded polyurethane insole relieves pressure to ensure a comfortable ride, even when using the trainer for extended periods.
An internal shank, located in between the outsole and the midsole, reinforces the arch area. It forces the foot to flex at the forefoot to not stretch out the arch and prevent injuries.
The upper of the New Balance 857 v2 uses leather with perforations in various areas that allow heat to dissipate.
The traditional lace-up closure uses round laces to keep the foot locked in place. The lightly padded tongue serves a layer of protection between the laces and the instep.
The collar, which is also slightly plush, prevents chafing of the ankle while also keeping it supported.
A pull loop at the back of the collar makes it easier for the user to put on the shoe.
An external heel clip anchors the foot to the midsole. This structure keeps the foot from slipping out of the shoe while in motion.
Lining the inside is Dri-Lex, a smooth fabric that wicks moisture away from the foot. This material also ensures a comfortable in-shoe feel and a quick on-and-off.
