Your Most Comfortable Shoes Might Be Wrong For Lifting
There's no best shoe for every type of exercise. There's a best match between the shoe, the type of workout, and the results you want.
Together with NOBULL
The 3-Minute Test Your Training Shoes Should Pass
Look through old photos from the Pumping Iron years, and you'll see Arnold squatting barefoot. Shoes were barely part of the conversation. The work was the iron.
Arnold has since said they knew much less then. Some of the knee, back, and foot pain everyone accepted as part of serious training may have come from wearing the wrong shoes, or no shoes when a pair would have helped.
But like so many things, Arnold was ahead of his time. Unlike running, barefoot training has many benefits, especially if you’re wearing the wrong shoes.
When under a heavy barbell (or really when holding any weight and trying to generate force, the surface beneath your foot should hold still.
But a no-shoes approach also has some limitations (not to mention, some gyms don’t love it).
And your shoes — at least the right shoes — have a job that’s far more important than looking good.
A running shoe is built to soften thousands of landings.
A lifting shoe needs to give you a stable base to push against.
A shoe for court sports or mixed training needs grip when you move sideways.
There is no best shoe for every workout. But there is a best match between the shoe and the work you want to do.
Don’t Miss It
If you want a special offer on the shoe we recommend, Pump Club readers get $50 OFF this weekend only. To access your discount, use the code APC50.
Comfort Is The First Test (But Not The Last)
Comfort matters more than shoe marketing admits. And that’s probably because “comfort” is more subjective.
In 2015, researchers proposed the "comfort filter": runners may naturally favor shoes that allow them to stay closer to their preferred movement pattern, which could reduce injury risk. It was a proposed model, not proof that the shoe that feels best will prevent injury.
But it aligns with what you see anecdotally and in studies: how you feel influences how you perform.
And that’s part of the difficulty with finding the right shoe.
A walk across a store can tell you about pinching, rubbing, and obvious fit problems. It can't tell you what happens when a barbell and your body weight press into the sole, or when you plant hard and change direction.
That is where the material under your foot matters.
Soft foam compresses. During a run, that can make repeated landings more comfortable.
During a heavy squat or deadlift, the same foam can make your heel sink or shift while you try to produce force.
One study had lifters squat at 60 percent of their one-rep max in running shoes and again in weightlifting shoes with a firm, raised heel.
The weightlifting shoes reduced forward torso lean, although squat depth and thigh angle at the bottom did not differ. The shoes changed the position. They did not transform the lift. But those little things shift how you feel and move, and they influence the comfort and confidence you bring to training.
Research on unstable-surface training helps explain the tradeoff.
Scientists found that unstable bases can reduce force, power, movement speed, and range of motion.
A cushioned shoe is not the same as standing on a balance device, so we shouldn't pretend that research proves soft shoes are dangerous.
