Long Femurs in the Squat: Should You Raise Your Heels?

What do long thighs actually change?

Here, “long femurs” means thighs that are relatively long compared with the lower legs or torso, rather than simply being tall. In a squat, these ratios may change the position needed for balance. They do not prescribe a depth or a single technique.

In a study of 32 young adults, a higher thigh-to-lower-leg ratio was associated with more knee and ankle flexion in narrow or medium stances during unloaded squats. The study did not test raised heels and cannot prescribe heel height from femur length.

What does raising the heels change?

Legg and colleagues compared raised-heel weightlifting shoes with athletic shoes in 32 adults during loaded and unloaded squats. With weightlifting shoes, measured ankle flexion decreased and knee flexion increased. The trunk was more upright without load; under load, the trunk effect was not significant in every group.

This is an immediate change in movement mechanics. The study did not group participants by femur length or measure hypertrophy or progress over several months. Raised heels are therefore an option to try, not an automatic correction for a body type.

How can you compare both versions fairly?

1. Choose your usual back squat variation, a light load and a consistent stance width.
2. Perform a few reps in flat shoes, then with a stable, equal heel lift under both feet. Avoid loose, unstable objects underfoot.
3. Compare similar depth and effort: foot contact, bar path and your ability to repeat the movement. Do not decide from one rep.

If you switch to the front squat, repeat the test: the load position changes too. The guide to squat stance width helps you settle your stance before comparing shoes.

When should you keep raised heels?

Keep this option if it makes your intended depth more stable and repeatable without losing foot contact or causing discomfort. If flat shoes already give you a controlled squat, there is no need to switch. Some torso lean is not, by itself, a fault to eliminate.

To assess it over time, keep the same variation, shoes and comparable depth for several sessions. Log sets, reps and weights in your workout log. The guide to full versus partial range of motion helps you avoid comparing a deep squat with a shallower one.

Sources and methodology

Both original studies were read in full. They measure immediate biomechanics; they do not show that raised heels improve long-term strength or muscle growth in people with long femurs. The comparison below is a practical guideline.
