Size & Care

You can find the information on this page here. 

For the best possible fit, consider the following guidelines when selecting ONDO socks. If you are in between sizes for our Organic Cotton and Merino Wool socks, we suggest sizing down to ensure a comfortable fit. However, for our Low-Cut socks, it's advisable to size up when you're in between sizes. If you happen to have wider feet and fall within the upper range of size, opting for a larger size is recommended. 

For any additional sizing inquiries or questions, please don't hesitate to reach out to us at

For the best care of your ONDO's socks:

  • Wash cold or at a delicate setting
  • Avoid dry cleaning, tumble drying, ironing, and bleaching
  • Always hang it to dry

It's as easy as that. Learn more about how to wash each of our styles here.
