Marie in Alaska deals with cold tootsies much of the year. She's found an economical way to make her son's socks slip-free:
When my toddler started walking, the kitchen floor became a slipping danger. We live in Alaska and it is cold more than it is warm, so allowing him to run around without socks was unacceptable. I bought a few pairs of socks with the non-slip designs on the bottom but it was hard paying so much for socks my little guy would outgrow so fast. I realized that the non-slip stuff on the socks felt very similar to the 'puffy' kinds of paints people use to draw designs on cloth craft projects. A pack of plain white socks and 3 tubes of puffy cloth paint later and we have ten pairs of non-slip socks that prevent my little guy from slipping across the kitchen! The best part is that we got ten pairs of socks for about $13. My husband and I had fun coming up with designs and words to draw/write on our son's socks! I'm actually looking forward to when he needs the next size up!
We've been using them for a couple months now and they've held up well. A couple have cracked a little but I think it is more because I didn't "stretch" those pairs before I painted them. And you do have to remember to turn them inside out when you throw them in the washer, which hasn't really been an issue for us but I guess could be for others.
My own preschooler is reluctant to wear her socks in the house after having one too many slips. I think I'll try this as a mother-daughter art project and see if "designing" her own socks gets her excited about wearing them.
