  • One of the most prominent features of the Merrell Vapor Glove 4 3D is its vegan-friendly build. Essentially, this means the materials and technologies of the shoe are made without the involvement of animals or animal-derived products.
  • The Vibram® TC5+ is an outsole technology that features arranged lugs to ensure that the shoe has a big grip on varied surfaces. This technology also increases the durability and protection of the shoe from different elements. 
  • The shoe employs the M Select™ FRESH. This helps with the odor elimination of the shoe and is incorporated in the inner sleeve of the Vapor Glove 4 3D. This contains anti-bacterial agents that break down the odor-causing bacteria inside the shoe to keep the shoe fresh after use. 
  • A 3D knit upper also helps with the flexibility of the shoe. This allows the runner to move the foot without any restraint.

The Merrell Vapor Glove 4 3D is available in standard sizing scheme for both men and women. However, to ensure perfect in-shoe experience and fit, it is advised to have actual testing of the shoe first before proceeding to purchase. An accurate fit can also be achieved by observing other users’ feedback on the sizing and fit of the shoe. 

Several technical elements affect the fit of the shoe. One of these is the shoe’s 3D knit upper that ensures the general sock-like fit of the shoe. The Hyperlock™ TPU molded heel counter, which helps secure the foot in place, also contributes to the shoe’s sizing. The Vapor Glove 4 3D also utilizes a traditional lacing system, which is also very common among other running shoes

Merrell Vapor Glove 4 3D employs Vibram® TC5+ as its outsole component. This technology is also incorporated into the Merrell Trail Glove 5. This helps ensure safety on any terrain, including level and sloping grounds. This technology also features front lugs that are arranged to gain a huge grip on irregular surfaces. 

An integrated insole is also incorporated into the Merrell Vapor Glove 4 3D to promote stability and added support. 

The Vapor Glove 4 3D’s Barefoot 2 construction helps the shoe balance both its anatomical fit and its zero-drop feature without sacrificing stability and underfoot protection. This technology basically helps with the proprioception—the ability of the foot to sense the surface it is on. To achieve this, Merrell carved out a support zone in the shoe’s midsole, which cradles the arch, while allowing the foot to move freely and to instantly adapt to its environment. 

The upper of the Vapor Glove 4 3D is made with 3D knit. This technology ensures that the shoe has a 360-degree sock-like fit. This feature of the shoe allows a secured in-shoe hug to the foot. 

To further the security of the shoe, a traditional lacing system is employed by the shoe. This promotes a lightweight feel when running while giving an adjustable fit. The shoe also uses a breathable mesh lining to enhance the support and security of the shoe even further. 

The shoe also sports a Hyperlock™ TPU molded heel counter- providing added support and security to the shoe, especially for long-distance trail running. This also serves as an added component for protection to the shoe from different elements when treading through trails. 

M Select™ FRESH is embedded on the inner sleeve of the Vapor Glove 4 3D. This contains reactive and friendly microbes that reduce the shoe odor. These anti-bacterial agents basically break down the odor-causing bacteria upon contact.
