Do You Actually Need Weightlifting Shoes? The 'No Heels, No Depth' Claim vs Research
Published:
Written by: Shingo YoshizakiReviewed by: Tomonobu Someda
Weightlifting shoes with elevated heels are said to increase squat depth and allow a more upright torso, earning them a following among strength athletes. Others argue you should develop the mobility to squat without heel elevation. Let's sort through the evidence.
Let the data settle it.
Weightlifting shoes improve squat depth and trunk angle
What's said
パワーリフティング・ウエイトリフティングコーチ、ジムでの通説
Heel elevation compensates for ankle mobility limitations, letting you squat deeper. For people with stiff ankles, they're essential.
What research says
- Research including Sato et al.
- (2012) and the Footwear squat kinematics study in this database confirms that heel-elevated shoes reduce trunk forward lean (more vertical torso) and increase knee travel.
- Squat depth (hip flexion angle) also tends to improve.
- However, the benefit is most pronounced in those with restricted ankle mobility — those with adequate dorsiflexion see limited additional gains.
Weightlifting shoes provide a clear benefit for trainees with restricted ankle dorsiflexion. For those with adequate mobility, they're not necessary. Whether to use shoes or invest in ankle mobility work depends on your goals and timeline.
Heel elevation increases knee stress and raises injury risk
What's said
フラットシューズ推奨コーチ、一部のスポーツ整形外科
Heel elevation pushes the knee too far forward, increasing compressive force on the knee joint and raising injury risk.
What research says
- The squat depth & knee load review in this database confirms that knee compressive forces increase with deeper squats, but remain within safe ranges for healthy knees.
- While heel elevation does increase knee travel, it simultaneously reduces trunk lean, redistributing load away from the lumbar spine and hips.
- Safety depends less on absolute knee load and more on whether joints remain within their functional range.
Increased knee load is real but within safe limits for healthy knees. In fact, the more upright torso from heel elevation often reduces lumbar spine load. Those with a history of knee injuries should consult a physician or physical therapist before deciding.

Are Cushioned Shoes Bad for Lifting? Myth vs Research
'Squatting or deadlifting in soft, cushioned running shoes lets your power leak away' and 'flat soles or barefoot are the only right choice for lifting' — you hear this a lot in gyms. So how much does shoe cushioning actually affect your lifting results or safety? We'll look at the biomechanics research, but up front: this area is very thinly studied. We'll honestly separate what we know from what we don't.

Do You Really Need a Lifting Belt? The 'No Belt = Injury' Claim vs Research
You'll often hear that 'a belt is a lifeline — squatting or deadlifting without one is dangerous.' But you'll just as often hear the counter: 'belts weaken your core' or 'you don't need one.' Let's examine the main claims around lifting belts against the research evidence.

The Valsalva Maneuver and Intra-Abdominal Pressure: How Breathing Technique Unlocks More Strength
The Valsalva maneuver — holding your breath and bracing to increase intra-abdominal pressure — is an effective technique that enhances both safety and performance on heavy compound lifts. However, it temporarily causes a sharp blood pressure spike, so anyone with cardiovascular disease or hypertension should consult a physician first.
