In a triathlon, the running stage is one of the most important and enduring parts of the competition. For triathlons, it’s the final stage and the last opportunity for competitors to shave down their time. It’s also the most grueling for many, as running a marathon after cycling and swimming is the toughest challenge of a triathlon for many entrants. One aspect triathletes can’t overlook is their gear—specifically, their running shoes.
One important aspect of finding the ideal endurance shoe for triathletes is drop height. In this guide, we'll walk you through everything you need to know about drop height. You'll learn what it is, how it's measured, and how it impacts your running mechanics. Discover how to compare drop heights in men’s running shoes to find the ideal pair for you below!
Understanding Drop Height
Drop height is a simple yet significant measurement. Drop height, also known as heel-to-toe drop or offset, is the difference in height between the heel and the forefoot of a running shoe. One way to imagine it is by drawing a straight line from the highest point of cushioning under your heel to the highest point under the ball of your foot. The vertical distance between these two points is the drop.
This measurement, typically given in millimeters, dictates the elevation of your heel relative to your forefoot while standing or running in the shoe. A higher drop means your heel sits much higher than your toes, similar to wearing a slight ramp. A lower drop creates a flatter platform, more closely mimicking a natural, barefoot stance.
How to Measure Drop Height
Shoe manufacturers determine drop height by measuring the "stack height" at both the heel and the forefoot. Stack height refers to the total amount of material between your foot and the ground. This includes the outsole, midsole, and insole. Subtracting the forefoot stack height from the heel stack height calculates the drop of the shoe.
For example, if a shoe has 30mm of cushioning under the heel and 20mm under the forefoot, it has a 10mm drop. It's important to remember that the overall amount of cushioning does not define the drop. A highly cushioned maximalist shoe and a minimalist shoe could both have the same drop height, even though they feel vastly different underfoot.
How Drop Affects Running Mechanics
The drop height of your running shoe directly influences your foot strike, the distribution of forces throughout your body, running efficiency, and injury prevention. A higher drop, typically 8mm or more, promotes a heel-striking pattern. The elevated heel makes it more natural for the back of your foot to contact the ground first. This motion can transfer more impact forces to your knees and hips.
Conversely, a lower drop, which ranges from 0mm to about 4mm, encourages a midfoot or forefoot strike. With a flatter platform, your foot is more likely to land more centrally or on the ball of your foot. This striking pattern shifts the initial impact forces away from the knees and more toward the Achilles tendon and calf muscles. Runners transitioning to lower-drop shoes often need to strengthen these areas to adapt to the new load.
The change in foot strike can feel more natural for some and may improve running economy by better engaging the body's natural shock-absorbing systems. Your individual biomechanics, injury history, and personal comfort will determine which pattern works best for you.
The Endurance Runner’s Guide to Different Drop Heights
Now that you understand the basics of drop heights in men’s running shoes, we can compare the different heights to determine which is ideal for you. The general drop-height categories to consider are high-drop, mid-drop, and low-drop (or zero-drop) shoes.
High-Drop Shoes (8mm and above)
High-drop shoes specifically benefit triathletes who experience fatigue in their lower legs. The elevated heel reduces the strain on the Achilles tendon and calf muscles, which the cycling portion of the race can severely fatigue before the running portion.
If you are a natural heel striker or have a history of Achilles tendonitis or calf strains, a higher-drop shoe could provide the support and relief you need to finish the run strong. Brands like ASICS and Brooks offer models in this category, providing a familiar, supportive feel for many athletes.
Mid-Drop Shoes (5mm to 7mm)
The middle ground of drop height shoes is mid-drop shoes. They provide a balance that works for a wide range of runners without forcing drastic changes in mechanics. For triathletes, these shoes can be an excellent choice if you're looking for a slight reduction in heel elevation without fully committing to the demands of a low-drop shoe.
This category accommodates both heel and midfoot strikers, making it a safe and adaptable option. Saucony and New Balance offer many popular models in this range that blend cushioning and responsiveness.
Low-Drop and Zero-Drop Shoes (0mm to 4mm)
Low-drop and zero-drop shoes promote a more natural running form. For triathletes with strong lower leg mechanics and a preference for a midfoot or forefoot strike, these shoes can enhance running efficiency. The flatter platform encourages a higher cadence and a more forward-leaning posture, which is advantageous for some runners.
However, transitioning to a low-drop shoe requires a gradual adaptation period to allow your calves and Achilles tendons to build the necessary strength. Brands like Altra, famous for its zero-drop platform, and HOKA, which offers some lower-drop options, are leaders in this category.
Finding Your Perfect Drop Height
Now that you understand the categories of drop heights for shoes and what they offer, you can better find the endurance running shoes that fit your body best. There is no single "best" drop height; the right choice is personal. If you frequently struggle with knee pain, a lower-drop shoe that encourages a midfoot strike might help. If calf or Achilles issues are your primary concern, a higher-drop shoe may provide more relief.
Next, think about your natural running form. If you're unsure of your foot strike, you can ask a friend to video you running or seek out a professional gait analysis. Matching the shoe's drop to your natural tendencies is the most comfortable and sustainable approach.
Finally, remember that comfort is king. The shoe that feels best on your foot is likely the one that will perform best for you. We encourage you to try on different models and see what feels most natural.

Choosing the right running shoe drop is a significant decision for any triathlete. It's about finding a tool that works in harmony with your body to help you achieve your goals. Whether you opt for a high-drop shoe to protect your calves or a zero-drop model to promote a natural stride, the key is to make an informed choice based on your individual needs.
Remember to transition slowly when making a significant change in drop height, giving your body time to adapt. Whatever type of shoe you want, we’ve got it in our extensive inventory of endurance footwear at T3 Endurance Sports! Shop online or stop by our store in Orem, Utah, today!
