Stack Height And Heel To Toe Drop Considerations

Stack height is the vertical distance from the ground to the footbed, typically measured at the heel and forefoot. Shoes with higher stack heights provide more cushioning material, which can feel protective but may also reduce the sense of direct contact with the terrain. Lower stack heights bring feet nearer to the ground and can increase ground feel.

Heel to toe drop, or simply “drop,” is the difference in stack height between the heel and the forefoot. Traditional running and hiking shoes often feature a moderate drop, while some models use lower or near-zero drops. Differences in drop can influence how the foot strikes the ground and how forces travel through the ankle, Achilles tendon, and lower leg.

Some hikers prefer moderate drops that feel familiar and can reduce strain on certain structures, particularly if they are accustomed to such footwear. Others find that lower drops encourage a more balanced stance and distribute loads differently. There is no single ideal drop; suitability depends on a hiker’s biomechanics, injury history, and comfort.

Changing either stack height or drop can alter how the body moves. Large or sudden changes in these dimensions may lead to discomfort if muscles and tendons have not had time to adapt. Many hikers transition gradually, using training hikes to allow their bodies to adjust.

Understanding stack height and drop helps hikers interpret footwear descriptions and make choices that align with their preferences and past experiences on trail.
