Below is a clear, beginner-friendly, step-by-step tutorial for making crochet slippers with no seam on the sole. This method is simple, customizable, and works with basic stitches. You can use it to make slippers for any size—adults or kids.

🧶 How to Make Crochet Slippers Without a Seam on the Sole (Beginner Tutorial)

These slippers are made in the round from the toe, so the sole is completely seamless, soft, and comfortable. The pattern uses basic stitches and is very forgiving.

✨ Materials You Will Need

Worsted weight yarn (Size 4) – about 150–200g for adult slippers
Crochet hook suitable for your yarn (usually 5.0 mm / H hook)
Scissors
Yarn needle for weaving ends
Stitch markers (optional)

📏 Sizing Guide (General)

These slippers are made from the toe outward, so you just try the toe cap against your foot until it fits.

Adult Small: 6.5–7.5″ foot length
Adult Medium: 8–9″
Adult Large: 9.5–10.5″
Child sizes: simply stop increasing earlier

🧶 Stitches Used

MR – Magic Ring
CH – Chain
SC – Single Crochet
HDC – Half Double Crochet (used after toe)
INC – Increase (2 stitches in same stitch)
SL ST – Slip Stitch

👣 Construction Overview

Start at the toe with a circle.
Increase evenly until the toe circle fits the width of your foot.
Work straight rounds (no increases) to form the top of the foot.
Create the heel using back-and-forth rows, but the sole stays seamless.
*Join the back with an invisible seam at the heel only.

🪡 Step-By-Step Instructions

STEP 1 — Start the Toe (Magic Ring)

Make a magic ring.
Round 1: 6 SC into the ring, pull tight.
Place a stitch marker if needed.

STEP 2 — Toe Increases (make a flat circle)

Work in continuous rounds:

Round 2: INC in each stitch → 12 SC
Round 3: 1 SC, INC around → 18 SC
Round 4: 2 SC, INC around → 24 SC
Round 5: 3 SC, INC around → 30 SC

👉 Keep increasing in this pattern until the circle covers your toes comfortably.
For adult medium, stop at 42–48 stitches depending on gauge.

Tip: Place the circle on top of your toes. When it fits the width well, stop increasing.

STEP 3 — Begin the Foot (no more increasing)

Switch to HDC for softer fabric:

Round 6+: HDC in each stitch around.

Continue until the piece covers your foot up to the start of your ankle.
This is usually 10–14 rounds, depending on your size.

You now have a tube shape.

STEP 4 — Shape the Heel (back-and-forth rows)

You’ll now stop working in the round.

Flatten the slipper and count the stitches.
Mark the heel opening (usually the back 60–70% of stitches).
Leave top-of-foot stitches unworked.

Example (for 40-stitch round):

Work only 28 stitches, turn.

Rows:

Row 1: HDC 28, CH 1, turn
Row 2: HDC across, CH 1, turn
Repeat until the heel reaches the desired depth
(usually 10–16 rows)

The piece will form a rectangle at the back.

STEP 5 — Close the Heel (no sole seam!)

Now pinch the heel rectangle together.

Use SL ST or a whip stitch with a yarn needle to close ONLY the back of the heel.
The sole remains completely seamless because we never stitched across the bottom.
