1. Lightweight design: Most indoor shoes are made of EVA or PVC material, with a weight of less than 200 grams, effectively reducing the burden of wearing and suitable for long-term home or fitness scenes.

2. Anti slip performance: Enhance grip in wet and slippery environments through techniques such as textured shoe soles and anti slip materials. Bathroom slippers often use PVC anti slip soles combined with crystal plush lining to achieve dual functions of anti slip and warmth.

3. Silent technology: Some styles use honeycomb shaped shock-absorbing structure midsole or frozen shaping process to reduce walking noise, suitable for quiet environments such as bedrooms.
