About two years ago, Claire Haeuptle, a
physical therapist based in San Diego, was interested in strengthening the
muscles and ligaments of her feet. Haeuptle, who played four years of collegiate
basketball, has a history of knee injuries, including five surgeries.

“I’ve always rehabbed my knees but have tended to
neglect my feet,” she said.
Haeuptle decided to take up barefoot weightlifting,
a strength training practice that involves lifting weights without shoes, or
with very little support for one’s feet.
Scrolling through social media platforms such as
TikTok, where the hashtag #barefoottraining has been viewed about 1.8 million
times, people show off barefoot dead lifts, curls and squats, while making a
number of claims about the benefits. The practice, according to its proponents,
can strengthen your feet, improve your balance, and help you lift more weight.
But, as with so many other fitness claims, the benefits come with a number of
risks, including injury, if done incorrectly.
Barefoot
weightlifting may have real benefits
Going barefoot — whether running, strength training,
or simply walking around — requires the muscles of the feet to work harder.
Some experts argue that this is especially true for smaller muscles that are
not used as much when wearing shoes, such as the abductor hallucis, which spans
the arch of your foot and controls the big toe, or the posterior tibialis,
which supports the arch.
“When you go without a shoe, these muscles start
working more, which ultimately give you a stronger and more adaptable foot,”
said Dr Bruce Moseley, an orthopedic surgeon at
Baylor College of Medicine.
Spending more time barefoot may also increase the
ability to sense where your feet are in space, as well as how they move. This
greater body awareness, known as proprioception, can contribute to better
balance by improving the feedback between the brain and the nerves in your
ankles and feet. Research focused on barefoot weight training is limited, but
it is possible that proprioception can help you maintain stability while
lifting, Moseley said.
It will not
necessarily help you lift more
Barefoot weight training may encourage increased
foot strength, balance and stability, but there’s no clear evidence it can
drastically enhance your performance or help you lift more. “It’s all
anecdotal,” said Kevin Valenzuela, an assistant professor of biomechanics at
California State University Long Beach, who was an author of a recent study
exploring the effect of footwear on dead-lifting performance.
In the study, published in the journal Sports,
Valenzuela and his colleagues looked at the dead-lifting performance among
barefoot lifters and those wearing shoes. They found no significant difference
in performance between the two, although dead lifting with shoes required a
little bit more work.
“When you wear
any sort of a shoe, you are about an inch higher than you would be if you were
barefoot,” said Anna Swisher, a USA Weightlifting coach. “You’ve got an inch
more to move the bar.” This extra inch may not make much of a difference for a
single lift but can add up over the course of a training cycle.
Heavy lifts require
dedicated lifting shoes
Lifting a percentage of your body weight will not
place too much of a strain on your foot, but when lifting significantly more
than you weigh, proper shoes become essential, as this puts a greater load on
the foot than it is capable of handling, said Dr Emily Splichal, a podiatrist
and author of the book “Barefoot Strong: Unlock the Secrets to Movement
Longevity.” As Splichal notes, many lifters will do warmups and lighter lifts
barefoot, and then, as they push higher, put on weightlifting shoes.
Most dedicated weightlifting shoes have hard, dense,
incompressible soles. “It’s easier to balance and it’s much more stable,” said
Mark Rippetoe, a weightlifting coach and author of the book “Starting Strength:
Basic Barbell Training.”
Lifting shoes also feature wedged heels that tilt
the foot forward, and, in Swisher’s experience, the stability they provide can
you help maintain good form, which is especially critical during weighted
squats. “Having that extra lift in the heel helps keep your torso more upright,
which helps keep the center of mass of the barbell more in line with your
center of mass,” Swisher said. This reduces the amount of pressure placed on
your lower back, which can help prevent injury.
Even during lighter
lifts, there are risks
Although barefoot weightlifting can offer benefits,
all of the experts, including Haeuptle, warned there are a number of risks,
including the potential for injury, if not done properly.
One major problem with barefoot weightlifting is
that “some people don’t have the ankle stability to do it well,” Valenzuela
said. If a person with weak ankles starts weightlifting barefoot, this can lead
to the ankles wobbling.
This ankle wobbling can cause the arches of the feet
to collapse inward, which gradually leads to the knees and hips collapsing
inward as well. “That inward rolling motion is usually not a great thing for
the joints and the tissues within the joints,” Valenzuela said. Over time, this
can lead to ankle, knee, or hip injuries. “What happens at the ankle affects
what happens at the knee, which affects the hip,” Valenzuela said.
If you are thinking about taking up barefoot
weightlifting, be extra mindful about the stability of your ankles, which might
mean doing ankle-strengthening exercises before you begin. Until then, it’s
best to wear lifting shoes, as they will provide additional ankle support.
Barefoot lifting also comes with a few additional
warnings. The first concern is that going barefoot in a gym can spread
infectious diseases, such as athlete’s foot or warts. “Athlete’s foot, once it
gets in a locker room or training environment, can run rampant,” Moseley said.
If you’re concerned, there are barefoot-style training shoes you can wear.
The other risk is foot injuries. Although shoes will
not do much if you drop a 20kg weight, they may offer some protection against a
lighter weight or a stubbed toe.
To avoid overuse
injuries, start gradually
Lifting too much too soon can lead to overuse
injuries, such as stress fractures or heel pain. But starting with a reduced
weight and a limited number of barefoot repetitions will “gradually apply the
stress to these tissues,” Moseley said, which lets the tissues of your feet
adapt.
If a person starts developing foot pain, or their
form suffers, that’s a sign they are lifting too much, too quickly, and should
stop.
Haeuptle started gradually, taking a full year to
progress from a few barefoot reps during a workout to doing the majority of her
lifts without shoes. Barefoot weightlifting “gives me a better sense of the
ground,” she said.
