Great for Sensitive Kids
My kiddo hates most socks but loved these the moment they were on. The seamless toe is brilliant.

Not seamless
I bought these because they are marketed as seamless, and my son REALLY hates an uncomfortable seam in his sock. They do have a seam, and he still asks me to readjust his sock multiple times. They’re cute, but not what I was hoping for.

Heel Color by Size
LOVE that different sizes have a different colored heel - I was able to buy these for our 8 year old AND our 5 year old, who wants what his big brother has! They fit and look great!

High quality, kid loves them
I had only ever purchased a raincoat from Primary (still very pleased with that!) — happy I chose to look here for socks. The first day he wore them, my 4 year old said “these socks are so soft!” and “these socks are so warm!” at least 8 times. Have washed and worn several time, and I can tell they are high quality. And I always appreciate the grippy dots on the bottom! For these, I also love the size color coding on the heel/toe, because I struggle differentiating sizes during the laundry overlap when transitioning to the next size up. Already planning to buy these again when my kid outgrows the current socks. One recommended improvement: extend color coding from heel across the whole base of the foot to the to toe. Since the sole of socks get so dirty.

Socks Up!
Wonderful everyday sock that holds up on the ankle/leg. On the thinner side, which my kiddos like. Clean classic look

Cute
Cute. I got large for my 10yold. She wears shoes size 3-4. The socks are nice and not too tight on her. She's on the thing size

Pretty obsessed
I needed to get my 5 year old some new socks as he’s been outgrowing his current pairs and thought the design of these were cool and simple. What I didn’t expect is that my kid would be obsessed with them and doesn’t want to wear any of his former socks. Why? The toe and heel guide. I didn’t realize how much easier and faster they make it for him when he puts on his own socks. And the grip on the bottom is much better than other pairs of his so he can run in the house with them even against my advice. It’s the little things.

Perfection
We love these socks! Every time my daughters put them on the gush over how soft they are. Wish they came in more colors!

Great socks!
My son loves how soft these are! Even though I prefer the look of an ankle sock, he likes "tall" socks and these are an attractive option. They are pricey but Primary usually holds up well over time so I decided to buy a second pack.

The only socks my kids will wear!
Both of my boys (4 and 5) love these socks. They're soft, wash well and support their independence in self dressing. I love the color coding for laundry day and the fact that we don't have morning freak-outs with my super sensory-sensitive eldest, thanks to the no-seams 🙌🏾
