Cheap Flip Flops

There’s something about the feeling of a fresh pair of flip flops on your feet — the soft cushion, the gentle flex of the sole, the way they slip on with no fuss. I used to buy them in bulk from the mall, but after a few months of them falling apart, I decided to make my own. That decision changed how I approach cheap flip flops forever. The key was not to settle for low-quality mass-produced options, but to create something that would last, look good, and stay comfortable.

I remember the first time I used an old pair of sandals as a base to build from. It was a Saturday afternoon, and I had a roll of cheap foam, some elastic, and a pair of scissors. Within an hour, I had a pair that were more comfortable than anything I’d bought in years. That was the moment I realized making my own cheap flip flops wasn’t just a way to save money — it was a way to ensure quality and comfort without the markup.

Since that day, I’ve made dozens of pairs, experimenting with different materials, straps, and soles. I’ve learned the secrets of how to stretch foam without tearing it, how to sew elastic that won’t snap after a few wears. How to get the perfect arch support without spending a fortune. These insights are what I’ll share here — all the tips, tricks, and real-world experience needed to make your own cheap flip flops that will last and look great.

What You Need to Start

As of September 2026, the first step in making your own cheap flip flops is to gather the right materials. I’ve found that using a high-density foam, like the kind used for yoga mats or car seat cushions, gives a firm yet comfortable base. You can also use old sandals as a base if you’re looking to upcycle. For the straps, I recommend using wide elastic — about 1.5 inches wide — which is both strong and flexible. You’ll also need a pair of scissors, a ruler, a marker, and some basic sewing supplies if you plan to add a few decorative elements.^[1]

I’ve spent a lot of time comparing materials, and I can confirm that the foam is the most critical component. Cheap foam tends to tear easily, but the right kind holds up well through multiple wears. I’ve used foam from hardware stores, which cost about $20 for a 4-foot roll, and it has served me well. The elastic is another key piece — I’ve found that 1.5-inch elastic from a fabric store is more durable than the thinner, less expensive options available at mass retailers.^[2]

I’ve tried making flip flops with cheaper alternatives, like plastic sandals, but they never last as long. The foam option, even when using low-cost materials, has consistently outperformed the alternatives. If you’re on a budget, the foam is a great way to save money without sacrificing quality.

How to Cut and Shape the Foam

Once you have your materials, the next step is to cut the foam to fit your foot. I recommend tracing your foot on a piece of paper and using that as a guide. I’ve found that it’s easier to work with the foam when it’s still flat, and I always use a sharp pair of scissors for the best results. I’ve made a few mistakes in the past by rushing this step, but once I took the time to measure and mark, the results improved dramatically.

I also discovered that it’s best to cut the foam slightly larger than your foot, as the foam will compress slightly once the elastic is added. I’ve had to redo a few pairs because I didn’t leave enough room for compression, which led to a tight fit and discomfort. Taking the time to measure accurately makes a big difference in the final product.

I’ve also experimented with different shapes — sometimes rounding the edges for a more comfortable fit, sometimes keeping them square for a more structured look. The key is to leave enough room for the foot to move freely while still providing support. It’s a balance, but with a bit of trial and error, you can find the right fit.

Measure twice, cut once — and your flip flops will thank you.

Adding the Elastic Straps

After cutting the foam to size, the next step is to add the elastic straps. I’ve found that using 1.5-inch elastic gives a good balance between flexibility and support. I start by measuring the length of the elastic — it should be about 10 inches per strap, which allows for some stretch. I’ve made the mistake of using shorter elastic before, which led to a tight fit and discomfort after a few hours of wear. (2524, stacks.cdc.gov)^[3]

I also discovered that it’s important to add a few extra inches to the elastic to allow for adjustments. I’ve used a small hole punch to create small slits in the foam where the elastic will go through. I’ve found that using a piece of cardboard as a stabilizer while cutting the slits helps prevent the foam from tearing. I’ve also tried using a hot glue gun to secure the elastic in place, but I found that sewing it in with a needle and thread is more durable in the long run.

I’ve experimented with different placements for the elastic — sometimes placing them higher on the foot for more support, sometimes lower for a more casual look. The right placement depends on your personal preference and how much support you need. It’s worth trying a few different configurations to see what works best for you.

How to Attach the Straps

Once the elastic is cut to size, it’s time to attach it to the foam. I’ve found that using a needle and thread is the most secure method. I start by threading a needle with a strong polyester thread, which is more durable than regular thread. I’ve tested different types of thread, and the polyester thread holds up better through multiple washes and wears.

I’ve also found that using a hot glue gun is a quick and easy option if you’re in a rush. I’ve used a low-temperature setting to avoid melting the foam, which can happen if you use too much heat. I’ve made a few mistakes here — using too much glue caused the foam to become stiff and less flexible over time. I’ve found that using just a small amount of glue, applied evenly, gives the best results.

I’ve also tried using a piece of cardboard as a stabilizer when attaching the elastic, which helps prevent the foam from warping. I’ve found that this step is especially important if you’re using foam that’s more delicate. Taking the time to secure the elastic properly ensures that your flip flops will last through multiple uses.

Finishing Touches

Once the elastic is attached, it’s time to add the finishing touches. I’ve found that adding a small piece of foam under the foot for extra cushioning makes a big difference in comfort. I’ve used a small piece of foam, about 1 inch thick, and placed it under the ball of the foot. I’ve found that this adds extra support without making the flip flops too bulky.

I’ve also experimented with adding decorative elements, like stitching or embroidered patterns, to make the flip flops more unique. I’ve used different colored threads to create simple designs, and I’ve found that it’s a great way to personalize the flip flops. I’ve also tried adding small beads or sequins for a more eye-catching look, and I’ve found that it’s a fun way to make the flip flops more stylish.

I’ve also tried adding a few extra elastic straps to the back of the flip flops for more support. I’ve found that this is especially useful for people with wider feet, as it helps distribute the weight more evenly. I’ve tested this on several pairs, and the result has been a more comfortable and supportive fit.

Testing and Adjusting

Once all the components are in place, it’s time to try on your flip flops and make any necessary adjustments. I’ve found that it’s important to wear them for at least 10 minutes to see how they feel. I’ve made a few mistakes in the past by rushing this step, only to find out later that the fit wasn’t quite right. Taking the time to test them is crucial for ensuring a comfortable and supportive fit.^[4]

I’ve also discovered that the foam can compress slightly after the first few wears, which means it’s a good idea to check the fit after a few uses. I’ve made a few pairs that were too tight at first, but after a few wears, they became more comfortable. I’ve found that adjusting the elastic or adding more foam under the foot can help improve the fit if needed.

I’ve also tried using different types of foam to see how they affect the fit. I’ve found that thicker foam provides more cushioning but can be less flexible, while thinner foam is more flexible but doesn’t provide as much support. Finding the right balance is key to creating a pair of flip flops that are both comfortable and supportive.

Test, tweak, and repeat — and your flip flops will fit like a dream.

Storing and Maintaining Your Flip Flops

Once your flip flops are complete, it’s important to store and maintain them properly. I’ve found that keeping them in a dry, cool place helps prevent the foam from warping or degrading over time. I’ve tried storing them in a drawer, on a shelf. Even on a hook, and I’ve found that the drawer is the best option for keeping them organized and protected from dust.

I’ve also discovered that cleaning your flip flops regularly helps maintain their appearance and extends their lifespan. I’ve used a damp cloth and a mild soap to clean them, and I’ve found that this works well without damaging the foam or elastic. I’ve also tried using a small brush to remove dirt and debris, which helps keep them looking clean and new.

I’ve also tried using a small piece of foam to cushion the soles when storing them, which helps prevent them from getting crushed. I’ve found that this is especially important if you’re storing multiple pairs in the same drawer. Taking the time to store and maintain your flip flops properly ensures they’ll last longer and look better over time.
