Summer is finally here.
The boots are packed away. The sneakers come off. And suddenly your feet are spending most of their time in sandals, flip-flops, slides, and other warm-weather favorites.
For many people, that change feels great at first.
Then a few weeks later, heel pain shows up.
The Achilles tendon starts feeling tight.
The ball of the foot becomes sore after a long day.
Or perhaps you’ve noticed your toes slowly starting to curl, overlap, or rub against your shoes.
What changed?
Often, it’s not your activity level.
It’s your footwear.
Why Summer Is a Common Time for Foot Pain
During the winter, most people spend months wearing supportive shoes. Even casual sneakers provide some degree of cushioning, stability, and support.
Then summer arrives and many people switch almost overnight to shoes that provide very little structure.
Your feet suddenly have to work much harder with every step.
For some people, that’s enough to trigger symptoms that have been quietly developing beneath the surface for months—or even years.
The result can be heel pain, Achilles tendonitis, arch fatigue, forefoot pain, and worsening toe deformities such as hammertoes.
The Flip-Flop Problem
Flip-flops may be the most common culprit.
Most flip-flops are completely flat, offer little shock absorption, and provide almost no arch support.
To keep them attached to your feet, your toes instinctively grip with every step.
Try walking across the room in a pair of flip-flops and pay attention to what your toes are doing. Most people are constantly clawing their toes to keep the shoe from slipping off.
That repetitive gripping changes the way your foot functions.
Over time, it places additional strain on the plantar fascia, the Achilles tendon, and the small muscles that help stabilize the foot.
It can also contribute to the progression of hammertoes.
When toes spend years repeatedly gripping sandals and flip-flops, the tendons and muscles that control them can become imbalanced. Initially the toes remain flexible, but over time they may begin to curl and stay in a bent position.
Many patients assume hammertoes are simply a normal part of aging.
While genetics certainly play a role, footwear choices matter too.
A short walk from the car to the beach probably isn’t a problem.
Wearing unsupportive flip-flops all day, every day throughout the summer is a different story.
Why Flat Sandals Can Trigger Heel Pain
One of the most common complaints I hear every summer is:
“My heel was feeling fine until sandal season started.”
Many sandals place your heel and forefoot on the same level, with very little support underneath the arch.
As a result, the plantar fascia absorbs more stress with every step.
If that tissue is already irritated or vulnerable, symptoms can quickly return.
Patients are often surprised because they haven’t changed their activity level.
The only thing that changed was what they were wearing.
Your Achilles Tendon May Not Like Your Sandals Either
The Achilles tendon experiences significant forces every time you walk.
Many athletic shoes have a slight heel elevation that reduces strain on the tendon.
When you switch to completely flat sandals, that support disappears.
The Achilles tendon suddenly has to stretch farther and work harder.
For some people, this leads to calf tightness, pain at the back of the heel, increased morning stiffness, or Achilles tendonitis.
This is especially common in people with limited ankle flexibility, arthritis, or underlying tendon degeneration.
Don’t Forget About Your Toes
Most people don’t think about their toes until they start causing problems.
You may notice one toe beginning to curl upward while another bends downward. You may develop corns on top of the toe or irritation from rubbing inside your shoes.
These are often early signs of hammertoe development.
Hammertoes don’t happen overnight.
They typically develop gradually as muscle imbalances, foot mechanics, and footwear choices work together over time.
If you already have a bunion, flat feet, or instability in the forefoot, the constant gripping required to keep sandals and flip-flops on can accelerate the process.
The earlier these changes are addressed, the easier they are to manage.
The Big Toe Plays a Bigger Role Than You Think
One of the most overlooked causes of foot pain is limited motion of the big toe joint.
The big toe is designed to bend upward during walking.
When that motion becomes restricted, the foot has to compensate elsewhere.
The arch may collapse more than it should.
The plantar fascia may experience increased tension.
The Achilles tendon may work harder.
The smaller toes may begin taking on forces they were never designed to handle.
This can contribute not only to heel pain but also to the progression of hammertoes and other forefoot problems.
Many flat sandals do little to support normal foot mechanics, making these underlying issues more noticeable.
What Makes a Good Summer Sandal?
A supportive sandal doesn’t need to look like a medical device.
Many modern sandals provide excellent support while still looking stylish.
When shopping for sandals, look for a contoured footbed that supports the arch rather than remaining completely flat. The sole should be relatively stable and not twist excessively. Adequate cushioning helps absorb impact, while straps that securely hold the foot reduce the need for toe gripping.
A slight heel elevation can also reduce strain on the Achilles tendon.
One simple test is to pick up the sandal and try to twist it.
If it folds into a pretzel, it probably isn’t providing much support.
What If You Need Orthotics?
One challenge with summer footwear is that many sandals cannot accommodate traditional orthotics.
Fortunately, there are sandal options specifically designed for people who need additional support.
For patients dealing with chronic heel pain, Achilles problems, hammertoes, or significant biomechanical issues, choosing the right sandal can be just as important as wearing the right athletic shoe.
The goal isn’t simply comfort.
The goal is improving the way forces move through your foot with every step.
You Don’t Have to Give Up Sandals
This isn’t about avoiding sandals altogether.
It’s about choosing the right sandal for the right activity.
Your favorite flip-flops may be perfectly fine for a quick trip to the pool or beach.
They may not be the best choice for a day exploring Portland, walking through Lisbon on vacation, spending the afternoon gardening, or attending summer festivals.
The right footwear can help prevent pain before it starts.
Don’t Let Your Shoes Ruin Your Summer
If heel pain, Achilles pain, foot fatigue, or worsening hammertoes seem to show up every year when sandal season arrives, your footwear may be part of the problem.
At Lighthouse Foot and Ankle Center, we evaluate not only the source of your pain but also how your shoes and foot mechanics contribute to it.
Sometimes a simple footwear change can make a dramatic difference. Other times, custom orthotics or additional treatment may be needed to address the underlying problem.
The sooner you address it, the more comfortable you’ll be throughout the summer.
