Danner - Tips for Sizing
- Measure both feet. If one foot is slightly larger than the other, select a size that fits the larger of the two.
- Consider the type of socks you’ll be wearing with your boot. For thicker socks, you may want to select a half size larger than you normally wear.
- When you do receive your boots, we recommend first wearing them indoors for a few hours to ensure they’re the right fit.
TURTLESKIN GLOVE SIZING
To make sure you get the best comfort, protection, and satisfaction, TurtleSkin Glove sizes are based on accurate hand measurements.
TurtleSkin Gloves come in many sizes to best fit you. Please use these charts to find your best glove size.
NOTE: Use the longest "finger length" or "hand width" measurement to find your size. If your longest measurement falls between sizes, order the larger size.
Hand Width Measurement: Wrap a tailor's measuring tape around your dominant hand just below knuckles, excluding your thumb, and make a fist. This measurement is your "hand width" glove size.
