Granny Slide Slippers

Transform a simple pair of store-bought slides into vibrant, cozy custom footwear with this fun granny square upcycle project.

Have you ever spotted a cheap pair of plastic slides at the dollar store and thought, "These could be so much better"? I certainly have.

There is something incredibly satisfying about taking a basic, utilitarian item and giving it a handmade, colorful makeover.

Traditional crochet slippers are wonderful, but they often wear out quickly on the bottom if you walk on hard floors. On the other hand, making slippers with proper soles usually means wrestling with thick rubber, punching holes with sharp tools, and struggling to work your hook through stubborn materials. It can be a real headache, especially if you just want a quick, relaxing project.

That is where this clever upcycle comes in.

Instead of crocheting an entire sole or piercing rubber, you simply crochet a stylish, shaped toe cover and attach it directly to an existing pair of slides. You get all the comfort and durability of a sturdy store-bought sole combined with the cozy, nostalgic charm of handmade crochet.

This project is incredibly beginner-friendly.

If you can make a classic granny square, you can easily conquer this pattern. We will start with a simple square, build up the sides with clever stitch heights to shape the toe, and then secure it to our base. It is the ultimate stash-buster and a fantastic way to customize your summer or indoor footwear.

Pattern Notes

• Skill Level: Easy / Advanced Beginner.
• This pattern is written in US crochet terms.
• The item is worked flat after the initial central granny square is completed in the round.
• All rounds of the central granny square are worked with the right side facing you. Do not turn your work.
• Tension Tip: Crochet your first toe top completely and place it over your slide. If it is too loose, drop down a hook size. If it is too tight, go up a hook size.
• Customization Tip: Weave in your yarn tails as you go by crocheting over them. Since these slippers won't go through a heavy washing machine cycle, this is a brilliant time-saver!

Step-by-Step Instructions

Crocheting the Central Granny Square

Round 1: Using your white yarn, ch 4. Join with a sl st to the very first ch to create a ring. Ch 3 (this counts as your first dc). Work 2 dc into the center of the ring, then ch 2 to create your first corner space. *[Work 3 dc into the ring, ch 2]* three times. Join with a sl st to the top of your starting ch-3. Fasten off, but do not turn. (You should have 4 distinct dc groups).

Round 2: To make weaving in ends easier, always join your new color in the ch-2 corner space right before your previous fastening-off point. Join your yellow yarn with a sl st in that corner. Ch 2 (counts as a dc here and throughout). Work 2 dc, ch 2, and 3 dc all in that same corner space. *[Skip the next 3 dc stitches, then work (3 dc, ch 2, 3 dc) in the next corner space]*. Repeat from * two more times. Join with a sl st to the top of your starting ch-2. Fasten off. Do not turn. (8 dc groups).

Round 3: Join your pink yarn with a sl st in the corner space right before your last fastening-off point. Ch 2, 2 dc, ch 2, 3 dc in that same corner space. *[Work 3 dc in the space between the next two dc groups, then work (3 dc, ch 2, 3 dc) in the next corner space]*. Repeat from * two more times. Work 3 dc in the final space between groups. Join with a sl st to the top of your starting ch-2. Fasten off. Do not turn. Your basic granny square is now complete!

Shaping the Right Side Rows

Row 1: Join your white yarn with a sl st in the corner space before the fastening-off point. Ch 2, work 1 dc in that same corner space. Work 3 dc in the next gap between groups, and 3 dc in the following gap. End by working 2 dc in the next corner space. Fasten off, but do not turn.

Row 2: Join your yellow yarn with a sl st to the top of the starting ch-2 from Row 1. Ch 2. Work 3 dc in each of the next 3 gaps between groups. End with 2 dc worked directly into the top of the last dc of the previous row. Fasten off, but do not turn.

Row 3: Join your pink yarn with a sl st to the top of the starting ch-2 from Row 2. Ch 2. Work 2 dc in the next dc, 1 dc in the next stitch, 1 hdc in each of the next 4 stitches, and 1 sc in each of the next 5 stitches. Fasten off.

Shaping the Left Side Rows

Row 1: Join your white yarn with a sl st in the opposite corner ch-2 space. Ch 2, work 1 dc in that same space. Work 3 dc in the next gap, 3 dc in the following gap, and end with 2 dc in the next corner space. Fasten off, do not turn.

Row 2: Join your yellow yarn with a sl st to the top of the starting ch-2 from Row 1. Ch 2. Work 3 dc in each of the next 3 gaps. End with 2 dc on top of the last dc of the previous row. Fasten off, do not turn.

Row 3: Join your pink yarn with a sl st to the top of the starting ch-2 from Row 2. Work 1 sc in that same stitch, then 1 sc in each of the next 4 stitches. Work 1 hdc in each of the next 4 stitches, 1 dc in each of the next 2 stitches, and 1 dc in the last stitch. Work a second dc in that same last stitch, but as you complete the final pull-through (when you have 2 loops left on your hook), YO and draw through your white yarn to join it.

Adding the Borders

Bottom Border: With your joined white yarn, ch 3. Working along the longer base side of the piece: work 2 dc across the end of the pink row, 2 hdc across the end of the yellow row, and 3 sc across the end of the white row. Work 1 sc in each stitch across the center until you reach the side rows on the other side. Work 1 sc in the next space, 3 sc across the end of the first white row, 2 hdc across the end of the yellow row, and 3 dc across the end of the pink row. Fasten off.

Top Border: Join your white yarn with a sl st to the top right corner of your toe top. Work 1 sc in that same corner. Work 2 sc across the end of the yellow row, 3 sc across the end of the white row, and 1 sc in each stitch across the center until you reach the side rows on the other side. Work 1 sc in the next space, 3 sc across the end of the white row, 2 sc across the end of the yellow row, and 1 sc in the corner. Fasten off.

Assembly and Attachment

First, weave in any remaining yarn tails cleanly.

Position the completed toe top over your slide. You can secure it using fabric glue or sew it on with a needle and matching sewing thread.

I highly recommend sewing! It gives a much cleaner, more durable finish around the edges. If you do use glue, use pins to hold the crochet piece firmly in place while it dries, and double-check the corners once dry.

When attaching, sew the left and right sides down first to ensure the slide underneath is fully covered.

Next, sew along the top and bottom white borders. To hide any slight size differences between your crochet piece and the slide, sew about an inch on the left and right sides, leave a small gap, and then sew a little in the middle.

Easy Variations & Custom Ideas

• Solid Colors: If you prefer a modern, minimalist look, skip the color changes and crochet the entire piece in a single solid neutral shade.
• Cozy Wool Blend: Swap the acrylic yarn for a warm wool blend to make these extra cozy for winter wear.
• Matching Family Sets: Make matching pairs for everyone! You can easily adapt this idea for kids using our Crochet Baby Slippers Pattern or make a cozy pair for your partner using the Everyday Mens Crochet Slippers.
• Summer Sandal Style: If you want a more open, strappy look instead of a full slide, try making the Blair Baby Sandals Pattern for the little ones in your life.
• Embellishments: Add a playful touch by sewing a small crochet flower or a flat button to the center of each granny square.
• Colour ideas: Try a retro 70s palette with mustard yellow, burnt orange, and cream, or go bright and beachy with turquoise, hot pink, and white.
• Yarn substitutions: Any soft worsted weight yarn like Red Heart Soft, Paintbox Yarns Simply Aran, or even a double strand of DK cotton yarn will work beautifully.

Common Troubleshooting & Fixes

• Problem: The toe top is too wide and hangs over the sides of the slide.
  Fix: Your tension might be a bit loose. Try remaking the piece using a hook that is one size smaller (e.g., switch from a 4.5mm to a 4.0mm hook).
• Problem: The corners of the crochet piece are peeling up after gluing.
  Fix: Fabric glue can be tricky on slick plastic. Use a strong, flexible craft glue (like E6000) specifically rated for plastic-to-fabric bonding, and secure the corners with binder clips while drying.
• Problem: The stitches look distorted or stretched when pulled over the slide.
  Fix: Ensure you aren't pulling the piece too tightly during assembly. It should lay flat and snug over the slide without being warped.
• Problem: The yarn tails are popping out after wearing the slippers.
  Fix: Since slippers experience a lot of movement, simply crocheting over the tails might not be enough for high-friction areas. Use a tapestry needle to weave the tails back and forth in opposite directions to lock them in place.

Care Instructions

Because these slippers are attached to plastic or rubber soles, do not throw them into the washing machine or dryer. To clean, gently spot-clean the crochet upper with a damp cloth, mild detergent, and cool water. Let them air dry completely in a well-ventilated area away from direct sunlight.

Final Thoughts

Upcycling store-bought slides with a touch of handmade crochet is such a satisfying way to express your creativity. It is fast, practical, and makes a wonderful gift for friends who love unique fashion. I hope you have as much fun mixing colors for your slides as I did! Happy crocheting!
