I bought a pair of socks for my 12 MO granddaughter who I look after during the day, we have tiled floors in the kitchen and I liked the idea of the grips on the bottom.
I followed the instructions and washed before wearing and although very pretty and lovely and soft they don’t stay on. My granddaughter is a little crawler still and they just work their way off or she pulls them off . Having said that my granddaughter loves them and the feel of the grippy bits and carries them around with her, so although not used in the conventional way, it’s a 👍from both of us .
