Summer Foot Care: How Your Sandals Could Be Harming Your Feet

Summer Foot Care: key facts at a glance.

⚡ Quick Answer

Summer sandals, particularly flip-flops, can put a real strain on your feet if you make the switch from supportive shoes too quickly. That sudden change in support levels forces your foot to work much harder, which leads to strain and a higher chance of injury. The trick to wearing them safely is to transition slowly, pick styles that actually support your foot, and pay attention to what your feet are telling you.

Your go-to summer sandals might be doing more damage than you think. While they're brilliant for keeping cool, popular choices like flip-flops provide very little in the way of arch or joint support. Podiatrist Dr Helen Branthwaite, who is the Chief Clinical Adviser at the Royal College of Podiatry, points out the real culprit isn't the sandal itself. It's the abrupt switch from structured, supportive shoes to flat, unsupportive footwear that causes the trouble. This sudden change puts your foot under a lot more strain than it's used to, and that makes you much more likely to get injured. Much like the sudden strain of a heatwave on the body, discussed in our guide to cardiovascular wellness summer uk heatwave nhs tips 2026, this transition can catch you off guard.

Getting your head around this risk is the first step towards happier feet this summer. This isn't about banning sandals from your wardrobe entirely. It's about picking them more carefully and making the transition safely. What follows is practical, medically-sound advice to help you enjoy the warm weather without ending up in pain.

The Real Problem With Flip-Flops

Flip-flops remain a summer staple for many people, and they've even had a bit of a fashionable revival lately with kitten heel versions. But their basic design still presents real challenges. As Dr Branthwaite explains, going straight from a very structured shoe to wearing flip-flops a lot means your foot is under more strain than normal. Your foot has to work harder, and that increased workload can lead to problems down the line.

What happens next is your foot's natural response to this change — it starts to adapt. Over time, the foot can begin to change shape and tends to splay a little. That splaying, when you combine it with the lack of support, can contribute to issues like plantar fasciitis (that's the heel pain people talk about), arch strain, and it can even start to alter your walking pattern. Which in turn could affect your knees and hips. The simple slip-on design, convenient as it is, often comes at a cost to your foot health that people don't really think about until it's too late.

How to Choose Supportive Summer Sandals

Not all sandals are created equal, and this is something worth remembering when you're shopping. Look for styles that offer more than just a flat sole. Prioritise sandals with a contoured footbed — one that gives you some arch support. Even a modest amount can make a real difference to how your feet feel at the end of the day. A deep heel cup is also good, because it helps to stabilise your foot and stop it sliding around.

🔬 Key Facts

The Science of Transition

→ Sudden switch is the main risk factor: It isn't the sandal itself, but the abrupt change from supportive shoes to flat footwear that causes injury.
→ Foot splaying occurs: Over time, the foot adapts to lack of support by changing shape and spreading out.
→ Chain reaction to joints: Altered walking patterns can eventually affect your knees and hips.
→ 2-3 weeks adaptation: A gradual introduction period allows muscles and tendons to adjust safely.

The Royal College of Podiatry advises against making a sudden switch. If you're used to wearing supportive trainers or work shoes most days, don't just start wearing completely flat sandals all day from the first sunny day. Introduce them gradually instead. Wear them for short periods at first, maybe an hour or two, and then slowly increase the time over a couple of weeks. This gives the muscles, tendons, and ligaments in your feet a chance to adapt to the reduced support without getting overstressed. It sounds simple, but it really does make a difference.

What To Do If Your Feet Already Hurt

If you're already experiencing some discomfort, the first thing to do is cut back on how long you're wearing the problematic sandals. Switch back to a more supportive pair of shoes for most of the day. Resting your feet matters, but gentle stretching can also help ease things along. Try rolling a frozen water bottle under your arch for a soothing kind of massage, or do simple toe curls and calf stretches. These are easy to do while you're watching telly.

Should the pain stick around for more than a few days, or if it's sharp, or if it affects your ability to walk normally — it's time to get professional advice. You can speak to your GP, who might refer you to a specialist, or you could book an appointment directly with a registered podiatrist or chiropodist. They can give you a proper diagnosis and may recommend specific exercises, padding, or even custom orthotics if that's what's needed.

Frequently Asked Questions

Are all flip-flops bad for your feet?

No, they aren't inherently bad for everyone. The issue, as the Royal College of Podiatry points out, is the abrupt transition from supportive footwear. Wearing them occasionally for short periods — at the beach or by the pool, say — is perfectly fine. The problems really start when people wear them as their main shoe all day long without their feet having had time to adapt.

What about fisherman sandals or other strappy styles?

It depends entirely on how they're built. The style name matters far less than the actual features. A fisherman sandal with a supportive, contoured sole and a secure fit can be a much better choice than a completely flat flip-flop. Always check the footbed for arch support and a stable heel before you buy. Don't just grab the first pair that looks nice.

Can I still wear kitten heel flip-flops?

The kitten heel adds some height and might change your balance a bit, but the core support issue doesn't really go away. A low heel can slightly reduce strain on the Achilles tendon, which is good. However, if the footbed itself is flat and unsupportive, you'll still face the same risks of splaying and strain. Prioritise the footbed's support over the heel height — that's the more important thing to look at.

How long does it take for feet to adapt to new sandals?

There's no set timeline, honestly. It varies from person to person quite a lot. That said, a gradual transition over two to three weeks is a sensible approach for most people. Pay attention to any aches or pains that show up. If you feel new discomfort, scale back the wear time and let your feet recover before trying again.

When should I see my GP about foot pain?

You should consider seeing your GP or a podiatrist if the pain is severe, doesn't improve after a week of rest and supportive footwear, if there's noticeable swelling, or if the pain prevents you from carrying out your daily activities. Persistent pain is your body's way of telling you something isn't right, so don't just push through it.

⭐ The Bottom Line

What this means for you

Enjoying the summer in sandals doesn't have to mean sacrificing your foot health. The main risk comes from making a sudden shift to unsupportive footwear like flat flip-flops, which can cause your feet to strain and splay over time. By choosing sandals with better support features, transitioning into them gradually, and actually listening to your body's pain signals, you can keep your feet comfortable all season long. If pain does show up, don't ignore it. Speak to your GP or book in with a registered podiatrist — getting on top of it early is always easier than trying to fix it later.
