Shopping for Flip Flops, Sandals, and Slides: A Foot Doctor’s Guide

As the weather warms up, many people switch to flip flops, slides, and sandals. While these open-toed shoes keep feet cool, they often lack arch support, leading to foot problems like blisters and heel pain. Fortunately, there are ways to stay comfortable and stylish throughout the summer.

What are some common foot problems caused by summer footwear like sandals, flip-flops, and slides?
People with flat feet, plantar fasciitis, Achilles tendonitis, or arch pain often experience flare-ups in summer because many sandals and flip flops lack proper arch support, compared with sneakers or closed-toe shoes.
It’s also difficult to wear orthotics in open footwear, which can worsen conditions like metatarsalgia (pain in the ball of the foot). Increased walking during summer vacations, especially on uneven surfaces like sand or cobblestones, can also aggravate joint pain and arthritis.
What features should I look for in flip flops, slides, and sandals to reduce strain on my arches and heels?
Look for summer footwear with arch support and a firm, inflexible sole. A good test: if you can fold the shoe in half lengthwise, it’s not supportive. Choose flip flops and sandals with rigid soles and built-in arch support.
Proper shoe sizing is also crucial—wearing the correct size improves comfort and makes arch support more effective.
If you suffer from Achilles tendon pain or heel pain, choose a sandal with a slight wedge, which mimics a heel lift used in some supportive closed shoes.
- Choose supportive summer footwear with arch support, rigid soles, and proper sizing to help prevent plantar fasciitis, heel pain, and Achilles tendonitis.
- Many brands offer stylish, foot-friendly sandals—If you have heel pain, look for options with a slight wedge heel for added relief.
- Use adhesive arch supports in open shoes and do daily foot stretches to reduce strain and improve flexibility all summer long.
Can you recommend summer footwear that is both supportive and stylish?
Many popular brands now offer supportive sandals in fashionable styles. These options provide both comfort and aesthetic appeal, so you don’t have to sacrifice style for foot health.
Are there any strengthening or stretching exercises to help offset the effects of wearing less supportive footwear?
Yes. Two effective exercises are:
- Plantar Fascia Stretch – Sit with your injured foot over your opposite thigh, so your legs are in a figure-four position, and pull your toes back to stretch the bottom of your foot. This simple foot stretch improves flexibility and reduces foot pain without equipment.
- Calf Stretch – Stand on a step with one heel hanging off the back. Hold for five minutes, twice a day. Helps with plantar fasciitis, Achilles tendonitis, and heel pain.

These foot strengthening and stretching exercises help reduce the strain from unsupportive shoes.
Can insoles or orthotics help in summer footwear?
Traditional orthotics are designed for closed shoes, but some adhesive arch support pads can work in open sandals. These can relieve pain in the arch and ball of the foot, especially for people with metatarsalgia. They’re a good option for making unsupportive footwear more tolerable. If you have pain in your feet, ankles, or even your knees and back, a podiatrist can determine if you need an orthotic. These are available in stores. A podiatrist can customize your orthotic to meet your individual needs.
What should I consider when buying or wearing shoes with heels?
Limit wearing high heels or stilettos for extended periods. Instead, choose high-heeled sandals with hidden platforms that reduce strain on the foot. Always match the heel height to your expected activity level. If heels are necessary, a block heel or wedge espadrilles (a light shoe typically made with canvas or cotton fiber) can be more supportive to your ankles as well.
What advice do you have for someone with bunions, bone spurs, or heel bumps?
For bunions, avoid tight or narrow-toed shoes. Look for open-toed sandals or those with soft fabric uppers to reduce irritation. People with heel bone spurs or pump bumps should consider backless shoes to avoid pressure and friction at the back of the heel.
