Founded with the belief that socks should be anything but ordinary, Happy Socks combines premium quality with vibrant, imaginative designs. The brand offers a comprehensive range of products including socks, slippers, swimwear, underwear and collaborative footwear, all designed with meticulous attention to comfort and style.

How to Measure

To ensure you select the correct Happy Socks size, follow these simple measurement steps. For the most accurate results, we recommend asking someone to assist you with taking your measurements.

  1. Foot Length: Measure from your heel to your longest toe. Place a ruler or measuring tape against a flat surface and position your foot perpendicular to it. Record the measurement in both centimetres and inches. This is the primary measurement for determining sock and slipper sizes.
  2. Foot Width: Measure across the widest part of your foot (typically across the ball of your foot). This measurement helps determine the appropriate slipper or pool slider width for a comfortable fit.
  3. Shoe Size Reference: Know your UK, EU or US shoe size. Happy Socks provides comprehensive size conversion charts to help you match your existing shoe size to the appropriate sock or footwear size.
  4. For Underwear: Measure your waist by wrapping a soft measuring tape around the narrowest part of your waist without pulling too tightly. Measure your length from your shoulder to your ankle to determine the appropriate garment length. Wear the tape comfortably, not too tight or too loose.
  5. For Swimwear: Measure your waist at its narrowest point and your inseam from your inside thigh to your ankle. Happy Socks swimwear is designed with a relaxed fit, so if your measurements fall between sizes, we recommend selecting the larger size.
  6. For Slippers: Measure the inside sole length of a slipper you currently own and enjoy wearing, or measure your foot length directly. Additionally, measure the width across the ball of your foot and the instep height for the most accurate fit, particularly if you have a higher instep.
Important: If your measurements fall between two sizes, we recommend ordering the larger size for optimal comfort. Happy Socks products are designed with a comfortable stretch, and proper sizing ensures longevity and comfort throughout wear. If you do order the wrong size, Happy Socks and most authorised retailers offer easy returns within 100 days.
