Check for a slip-resistant or non-slip label on the shoe or packaging
Look for outsole tread with deep grooves, channels, or textured patterns
Inspect the sole material for rubber or other high-friction compounds
Press the outsole with your thumb to see if it feels grippy rather than hard and slick
Compare the sole to certified slip-resistant standards or ratings if listed
Check whether the outsole is designed for wet, oily, or smooth surfaces
Look for a flat, wide contact area with multiple traction points
Avoid soles that are very smooth, glossy, or made of hard plastic
Read product reviews for mentions of traction, slipping, or workplace use
Test the shoes on a clean, slightly wet floor if safe to do so
