Your new favorite socks!

COLOR: Black

Traditional socks ruin a great outfit, and let's be honest... "no shows" always show or slip down and become annoying and uncomfortable. Put those pains to rest with FLAT SOCKS™!

These fun sock alternatives have a layer of foam for cushy comfort and are trim-to-fit, so they can be used in all your favorite shoes. The best part? Throw ‘em in the wash as often as you’d like.

  • NO SWEAT: Moisture-wicking pulls sweat away
  • SOFT & CUSHY: Supportive foam makes every step comfy
  • MACHINE WASHABLE: Throw ‘em in the washer & dryer, just like socks

Sizing Guide: We do not offer specific kid's sizing; however, all of our FLAT SOCKS™ are trim-to-fit. You can easily purchase a Small or Large pair and trim them down to fit any shoe size!

1. How do I trim FLAT SOCKS™ for my shoes?

  • EASIEST OPTION: If your shoe has a removable insole, take it out and use it as a guide to cut your new FLAT SOCKS™. This will ensure your perfect fit. NEXT EASIEST OPTION (only other option): The shoes your wearing don’t have a removeable insole, first, complain. THEN, count your blessings and flip your FLAT SOCKS™ over to find our trim guide on the back. Use this to cut down to your size!

2. Are FLAT SOCKS™ machine washable?

  • Yes, you wash them on a regular cycle with like-colors.
