Merrell Move Glove: Stack Height, Benefits, and Transitioning to Minimalist Footwear

What is the stack height of the Merrell Move glove?

The Merrell Move Glove is designed with a minimalist philosophy, featuring a low stack height typically around 14.5mm. This measurement encompasses the entire sole unit, from the ground to the footbed, emphasizing ground feel and promoting natural foot mechanics with a 0mm heel-to-toe drop.

Understanding Stack Height in Footwear

Stack height refers to the amount of material between your foot and the ground. It's typically measured from the ground to the top of the midsole, often including the outsole and any integrated footbed. This measurement is distinct from "heel-to-toe drop" (or offset), which is the difference in stack height between the heel and the forefoot.

Components of Stack Height:

• Outsole: The outermost layer providing traction and durability.
• Midsole: The primary cushioning layer (though minimal in barefoot shoes).
• Insole/Footbed: The removable or integrated layer directly beneath the foot.

A higher stack height generally means more cushioning and protection from impact, often found in traditional running shoes. Conversely, a lower stack height, characteristic of minimalist or barefoot shoes, is designed to enhance ground feel, proprioception (your body's awareness of its position in space), and encourage a more natural foot strike.

The Merrell Move Glove: A Minimalist Perspective

The Merrell Move Glove series is a prime example of minimalist footwear, engineered to mimic the experience of barefoot movement while offering a degree of protection. Its design priorities are:

• Zero Drop: A 0mm heel-to-toe drop means your foot lies flat, without the heel being elevated relative to the forefoot. This encourages a natural posture and can promote a midfoot or forefoot strike rather than a heel strike.
• Low Stack Height: As noted, the approximately 14.5mm total stack height is significantly less than typical running shoes (which can range from 20mm to over 40mm). This minimal cushioning allows for greater sensory feedback from the ground.
• Flexibility: The sole is highly flexible, allowing the foot to bend, splay, and move naturally, engaging intrinsic foot muscles.

The combination of zero drop and low stack height in the Merrell Move Glove aims to strengthen the foot and ankle, improve balance, and enhance the proprioceptive connection between the foot and the brain.

Implications of a Low Stack Height

The minimal stack height of the Merrell Move Glove carries several implications for the wearer:

Benefits:

• Enhanced Ground Feel and Proprioception: The thin sole allows for a more direct sensory experience of the terrain, which can improve balance and body awareness.
• Strengthened Foot Muscles: Without significant cushioning and support, the foot's intrinsic muscles are required to work harder, leading to increased strength and resilience over time.
• Promotion of Natural Gait: The zero drop and flexible design encourage a more natural foot strike (midfoot/forefoot) and toe-splay, which can be more efficient and potentially reduce impact forces when proper form is maintained.
• Improved Balance: Greater sensory input and active foot engagement can contribute to better overall balance.

Considerations:

• Reduced Cushioning: While beneficial for foot strength, the lack of substantial cushioning means less shock absorption, which can be challenging for individuals accustomed to highly cushioned shoes or those with pre-existing foot conditions.
• Increased Demands on Lower Leg Muscles: A transition to minimalist footwear requires the calves, Achilles tendon, and foot muscles to adapt to new loading patterns, potentially leading to soreness or injury if not introduced gradually.
• Form Emphasis: Proper running or walking form becomes paramount. Poor mechanics in minimalist shoes can lead to higher impact forces and potential injury due to the lack of protective cushioning.

Who Benefits from the Merrell Move Glove?

The Merrell Move Glove is an excellent choice for individuals who:

• Seek to strengthen their feet and ankles: Ideal for developing intrinsic foot muscle strength.
• Desire enhanced ground feel and proprioception: Beneficial for activities like trail running, hiking, or general fitness where sensory feedback is valued.
• Are transitioning to a more natural running or walking gait: Can aid in developing a midfoot or forefoot strike.
• Engage in functional fitness or weightlifting: The stable, flat platform can improve balance and power transfer during lifts.
• Are experienced minimalist shoe wearers: For those already accustomed to barefoot-style footwear.

It is crucial to understand that while a low stack height offers many benefits, it is not suitable for everyone, especially those new to minimalist footwear or individuals with certain biomechanical challenges.

Transitioning to Minimalist Footwear

Adopting shoes like the Merrell Move Glove requires a mindful and gradual transition to prevent injury and allow your feet and lower legs to adapt.

Key Transition Principles:

• Start Slowly: Begin by wearing the shoes for short periods, such as walking around the house or for brief walks.
• Gradual Increase: Incrementally increase wear time and distance over several weeks or months. Do not immediately use them for long runs or intense workouts.
• Listen to Your Body: Pay close attention to any discomfort or pain. Soreness is normal during adaptation, but sharp pain is a sign to rest or re-evaluate.
• Focus on Form: Emphasize a light, quick cadence with a midfoot strike, avoiding overstriding and heavy heel striking.
• Incorporate Foot Strengthening Exercises: Supplement with exercises like toe splay, calf raises, and arch lifts to prepare your feet for the demands of minimalist footwear.
• Alternate Footwear: Continue to wear your traditional shoes for activities that require more cushioning or during the initial transition phase.

Conclusion

The Merrell Move Glove, with its characteristic low stack height of approximately 14.5mm and 0mm heel-to-toe drop, is a purpose-built minimalist shoe. Its design prioritizes ground feel, natural foot movement, and the strengthening of foot and ankle musculature. While offering significant benefits for those seeking a more natural connection with their environment and improved foot health, a careful and gradual transition is essential to harness these advantages safely and effectively.
