I purchased these socks from Target in 2017-2019ish. They are Cat and Jack Brand and they had for 2T/3T and 4T/5T sizes. I don't know if they had bigger kid sizes at the time because my oldest was a toddler. These socks were so comfortable. They were soft and stretchy and my kids both loved them. I had mostly the 2T/3T sizes and only got one pack of the 4T/5T. My oldest has outgrown them and my youngest is about to.

This isn't my picture. The 4T/5T ones didn't have the little grips on the bottom.

These socks were so sensory friendly to my kids who both have survive sensory needs. My oldest just refuses to wear socks now, which we make work , but it's because of the feel of different socks and I would like him to have the option of keeping his toes warmer. I've tried a bunch of different socks from main brands that advertise as soft or stretchy, and ones that look right in Target but the material is totally different. It's almost like they felt like bamboo but thicker.

But we also don't live near a Target anymore so I can't go touch the ones in store.

I would love if someone knows of a really good sensory friendly kid sock that would fit kids shoe sizes!
