There is something wonderfully satisfying about slipping on shoes you made yourself, and crochet sandals ideas are the perfect summer project for exactly that reason. This roundup gathers 20 free patterns for women's open footwear with real soles and straps: 15 written patterns and 5 step-by-step video tutorials, so you can follow along in whichever format suits you best. From flip-flop soles transformed with cotton yarn to strappy gladiators, breezy espadrilles, and delicate barefoot styles for beach days, every design below is free to access in full.
Most of these sandals start with an inexpensive pair of flip flops, which gives you a sturdy, non-slip sole without any shoemaking skills, while the crochet upper is where all the personality lives. Pick a favourite, choose a washable cotton yarn, and stitch a pair that fits your feet and your summer wardrobe perfectly.
1. Crochet Flip Flops Upcycle
This clever upcycle turns a cheap pair of foam flip flops into pretty boho sandals with just a small crochet square and a tie. You start by crocheting around the existing straps, then add a simple square motif in the centre and finish with a long chain tie that wraps around the ankle. It is a wonderfully quick project, ideal for a first attempt at crochet footwear, and cotton yarn keeps the finished sandals washable and cool. Make them in a colour that matches your favourite flip flops, or go bold with a contrast shade for a real statement pair.

2. Crochet Women's Gladiator Sandals
These chunky gladiator sandals are made for women who want footwear with real presence, worked in super chunky yarn with a strappy, woven upper sewn onto a sole. The straps interweave over and under each other across the foot, giving that classic gladiator look without any complicated construction. Sized for adult women with clear gauge notes, the pattern works up fast thanks to the thick yarn, so a pair can easily come together over a weekend. Choose a neutral shade for everyday wear, or a bright colour for holiday evenings out.

3. Crochet Sandals Out of Flip Flops
If you have an old pair of flip flops with chewed or broken straps, this pattern gives them a second life as proper crochet sandals. You poke holes around the toe and heel of the sole, then crochet a toe section and a heel section directly into those holes, finishing with long ties that wrap around the ankle. The full instructions are written out on the page, and the whole project takes just a few hours from start to finish. It is a thrifty, eco-friendly make that feels especially good when the finished sandals look far more expensive than they were.

4. Crochet Espadrilles with Flip Flop Soles
These espadrilles capture the woven, summery look of classic rope-soled shoes using nothing but single crochet worked tightly over a flip flop sole. The toe is shaped row by row from the front of the sole, and pretty ribbon ankle straps finish the look with a preppy, yacht-ready feel. Sizes run from women's 5 to 10, and the pattern includes a printable ruler to guide your hole-poking so the stitches sit evenly around the sole. Try them in the red and ecru combination from the pattern photos, or in a soft neutral for a pair that goes with everything.

5. Dream Catcher Crochet Sandals with Flip Flop Soles
With their lacy, openwork upper and bohemian spirit, these dream catcher sandals are made for festival season and long beach days. The pattern is split into two free parts on the designer's blog, and it needs less than a skein of cotton yarn plus one inexpensive pair of flip flops. You only need single crochet, double crochet, slip stitches, and working in the round, so it is very approachable for a confident beginner. The airy fabric keeps feet cool, and the finished sandals look like something from a boutique rather than a dollar-store sole.

6. ARCADE Crochet Flip-flop
Named for the arcade stitch that shapes its pretty arched upper, this no-sew flip flop pattern works its stitches straight over the existing plastic straps, so the straps carry the weight rather than the yarn. The free written pattern comes with a full video tutorial with timestamps at the end of each row, so you will never lose your place. Worked in worsted-weight yarn with a 4 mm hook, it is a sturdy, comfortable sandal that holds up to real everyday wear. The arched stitch pattern looks far fancier than it is, making this a satisfying project for newer crocheters.

7. Crochet Sandals Using Flip Flop Soles
This beginner-friendly design uses only single, half-double, and double crochet to build a lacy sandal upper over a flip flop base, with both written instructions and a video to follow. The open arcade-style stitch keeps the sandals breathable, and the buttoned ankle strap adds a sweet, finished detail. Worked in a light DK yarn, the sandals feel soft against the foot while the rubber sole underneath handles pavements and pool decks with ease. It is a lovely weekend project that turns a plain pair of flip flops into something truly personal.

8. Crochet Over Flip-Flops Sandal
If poking holes in soles sounds like hard work, this no-sew sandal skips that step entirely by crocheting over the flip flop straps instead. The pattern offers three yarn weights, from fingering to worsted, each with its own hook size and stitch counts, so you can use whatever is already in your stash. A mesh-style upper with an ankle strap chain gives the sandals a light, summery feel, and the construction is simple enough for a relaxed evening project. It is a great choice when you want new sandals fast, with no special tools required.

9. Crochet Star Flip Flops
These cheerful flip flops are decorated with three crochet stars on each strap, each one finished with a bead at its centre for a touch of sparkle. The free downloadable pattern walks you through covering the straps in single crochet first, then making and stitching on the stars. It is a small, joyful project that is perfect for using up leftover yarn, and the star motif makes the finished sandals feel festive and fun. Make them in red, white, and blue for summer celebrations, or in soft pastels for everyday beach wear.

10. Embellished Crochet Sandals
Rather than building sandals from scratch, this pattern shows you how to give an existing pair of sandals a festival-ready makeover with overlapping crochet chains and bobble trim. You punch small holes along the sandal straps, then work colourful rows of double crochet across the front and ankle straps, finishing with a trimming of your choice. It is a brilliant way to rescue a plain pair of sandals or to coordinate them with a special outfit. Because you work with the sandals you already own, the fit is guaranteed from the very first stitch.

11. Not Granny's Gladiator Barefoot Sandals
Made entirely from granny squares, these statement barefoot sandals lace up the leg like true gladiators while covering the top of the foot in a pretty patchwork of squares. Six small squares and four large squares per foot join with mattress stitch, and a toe loop plus ribbon or chain lacing holds everything in place. Worked in size 10 crochet thread with a steel hook, they have a delicate, jewellery-like quality that dresses up bare feet beautifully. Each row can be a new colour, so they are a wonderful stash-buster for leftover thread.

12. Not Granny's Sassy Barefoot Sandals
The daintier sister of the gladiator style, these sassy barefoot sandals use just one large granny square and three small ones per foot, tied on with a simple slip-knotted thread.

The same size 10 thread and steel hook give a fine, lacy finish, and the simple construction means a pair comes together very quickly. Make a matching bracelet from the same squares for a complete summer set.
