Women's Gym & Training Shoes — What Cushioning Costs You Under a Barbell
Most shoes sold as 'training shoes' are cushioned running shoes. For lifting that's the wrong direction, and here's how to tell the difference.
By Azaz Khan · Published August 4, 2026
Quick answer
Most shoes marketed as training shoes are cushioned running shoes, which work against you under a loaded barbell because soft foam compresses unevenly. For lifting, look for a flat, firm heel; press your thumb into the heel and choose the shoe that barely moves.
Key takeaways
- A running midsole is designed to compress, which makes it an unstable platform under load.
- Press your thumb hard into the heel: if it sinks easily the shoe is built for cardio, not lifting.
- Viewed side-on, a raised wedge indicates a running shoe and a flat profile indicates a training shoe.
- Footwear pain-relief claims are frequently unsubstantiated and should not drive a purchase decision.
- If you split evenly between lifting and running, two cheaper pairs outperform one expensive compromise.

Search “women’s training shoes” and most of what comes back is a cushioned running shoe with different marketing.
For a lot of gym sessions that’s fine. For lifting it’s the wrong direction, and the reason is simple physics.
Cushioning works against you under load
A running midsole is designed to compress. That’s the whole point — it absorbs impact and returns some of it.
Under a loaded barbell, compression is the enemy. Soft foam squashes unevenly, your foot rolls, and the platform under you moves when it should be still. You lose force into the shoe instead of the floor.
A training shoe wants the opposite: a flat, firm heel that doesn’t move.
The 30-second test
Pick the shoe up and press hard into the heel with your thumb.
- Sinks in easily → cushioned. Good for cardio, bad for lifting.
- Barely moves → firm. That’s a training platform.
Then look at it side-on. A big wedge with a raised heel is a running shoe. Flat from heel to toe is a training shoe.
Match the shoe to your actual session
| Mostly… | Buy |
|---|---|
| Barbell work, squats, deadlifts | Reebok Nano Gym 1.0 |
| Classes, treadmill, bike | Under Armour Charged |
| Mixed, leaning cardio | Under Armour Charged |
| Standing all day, walking | Gravity Defyer |
If you genuinely split between lifting and running, two cheaper pairs beat one expensive compromise. Nothing does both well.
About pain-relief marketing
Some footwear in this category is sold with strong claims about relieving pain.
Be sceptical. Footwear pain-relief claims are frequently unsubstantiated, and “engineered to reduce impact” is a design description, not a clinical result.
That doesn’t mean a heavily cushioned shoe won’t feel better to you — it very well might, especially on hard floors. But buy it because you want cushioning, not because a listing implies it will treat a condition. If you have ongoing foot pain, that’s a conversation with a podiatrist, not a purchase decision.
What actually matters when you try them on
- Heel firmness — press it, as above
- Width across the ball of the foot — feet splay under load
- Heel lock — laces should hold your heel without you cranking them
- Sole flatness — look side-on, not top-down

#2 · Best for cardio and classes
Under Armour Charged
Under Armour
What we liked
- + Comfortable for treadmill, bike and class work
- + Typically the cheapest of the three

#3 · Best for standing and walking, not lifting
Gravity Defyer Energiya
Gravity Defyer

What we didn't

Our verdict
If you lift, the Reebok Nano Gym 1.0 is the pick here — it's from Reebok's Nano line, which is a genuine training range rather than a lifestyle sneaker wearing gym branding. If your sessions are mostly cardio and classes, the Under Armour Charged is the sensible choice. The Gravity Defyer is a heavily cushioned shoe for standing and walking, not something to squat in — a spring-loaded midsole is the opposite of what you want under a loaded barbell.
Frequently asked questions
Can I lift weights in running shoes?
You can, but the compressible midsole makes an unstable platform. Under load the foam squashes unevenly, the foot rolls, and force intended for the floor is absorbed by the shoe. For anything beyond light weights, a flat firm shoe is meaningfully better.
How do I tell a training shoe from a running shoe?
Two checks. Press your thumb hard into the heel: a training shoe barely compresses. Then look at the shoe side-on: a running shoe shows a thick wedge with a raised heel, while a training shoe is close to flat from heel to toe.
Do shoes marketed for pain relief actually work?
Treat such claims sceptically. Phrases like engineered to reduce impact describe a design intention, not a clinical outcome. A well-cushioned shoe may genuinely feel better on hard floors, but persistent foot pain warrants advice from a podiatrist rather than a footwear purchase.
