Pearl Izumi Transfer Air 7 in Sock

Measure your feet at the end of the day while wearing the socks you plan to wear with your shoes.

1. Width: Measure across the widest part of your foot, typically at the ball of the foot, while standing. Compare this measurement to the size chart if width options are available.
2. Length: Measure from the back of the heel to the tip of the longest toe while standing. Compare this measurement to the size chart to determine your best fit.

Feet are rarely the same size. Always use the larger measurement when selecting your size.

Footwear should feel secure without pinching or pressure points. If you are between sizes or prefer a roomier fit, sizing up half a size is recommended.
