Maxi-Cosi FamilyFix Slide Pro Car Seat Base
The Maxi-Cosi FamilyFix Slide Pro is an innovative ISOFIX base designed to simplify your daily routines while ensuring top-tier safety and comfort for your child. Equipped with Maxi-Cosi’s patented SlideTech™ technology, this base allows the car seat to slide toward you, making it easier than ever to get your child in and out of the car without straining your back.
Safety
With the FamilyFix Slide Pro ISOFIX base and compatible car seat, your little one is protected by long-lasting i-Size safety on every car journey. It locks securely into your car via ISOFIX connectors, while the support leg offers extra safety and stability. Visual indicators ensure correct installation of the base in the car and the car seat on the base.
Ease of use
SLIDETECH®2 lets you rotate and slide your car seat out of the car by 27 cm, the furthest slide ever. That makes getting your little one in and out of their car seat effortless — no backaches, head bangs, or struggles. You’ll never need to reach into the car to get your little one in or out of their seat ever again. You can also leave your car seat facing the door, making it even quicker and easier to get them into their seat ahead of your next journey.
Age range
When used with a compatible car seat, the FamilyFix Slide Pro base can be used from birth up to 4 years old. During that entire time, your child can always travel in the safest and recommended rearward-facing position, or in the forward-facing position, if preferred, from 15 months (76 cm).
Comfort
Your little one can enjoy the comfortable recline positions of compatible Maxi-Cosi car seats when attached to FamilyFix Slide Pro, as well as a lie-flat position when using a baby car seat. It also ensures maximum comfort for you when getting your child in and out of the car thanks to SLIDETECH®2, which is certified as back-friendly by AGR, the independent agency that promotes back health.

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all.
The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day.
They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable.
Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.
