Frequently Asked Questions

At what age is my child ready for a belt-positioning booster like the Tanza?

The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.

Can I install the Tanza without the UAS connectors?

The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.

Is the Tanza allowed on airplanes?

Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

Great shoes but seem to run bigger than other styles of Saucony
Size: 4 Wide Big Kid, Color: Navy/Pink
We pretty much stick with one or two brands. I have a kiddo with wide feet, who recently wore out her size 3 wides (big kid) in another pair of Saucony shoes, but she was also right at the end of the shoe, so I went with a whole size up. She picked these. The size 4's are enormous, so we had to pick another style in a 3.5w, as these didn't have 1/2 sizes and will hold on to these for fall. I picked up another brand in 4W that actually fit really well now, but they are not as heavy duty as these. I'm hoping the next style in a 3.5 isn't too small. Love these shoes, but the sizing on them feels less and less predictable. Compared to most shoes I have always had to size down in these, but now even between styles in their brand.n

Great shoes
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
This is a review for Saucony unisex child cohesion FST (little kid/big) size 1. These shoes are good quality and all the stitching is on point. They fit true to size for my daughter and the Velcro snaps are convenient for a little ones. I like the color of these ones as it looks cute. They have been comfortable wear and we’ve been out for hours while wearing them. I think they’re fairly easy to keep clean. I just wipe them down with a damp cloth and they come clean easily. I think these are a fair value as well and if you’re looking for a basic pair of shoes for your little one, I would recommend them.

Great play sneaker for outside
Size: 1 Little Kid, Color: Fuchsia
These sneakers fit my daughter’s feet perfectly and she loves the color. I trust the Saucony brand as I’ve owned several pairs. They are well made and this pair is an excellent option for play sneakers. My kids are outside a lot and I need a sneaker that can handle running, climbing and occasionally getting wet. There is generous breathable mesh and the shoes dry quickly. My daughter has slightly wider feet and these fit comfortably. I also appreciate that they are Velcro so can be put on or taken off quickly because we all know kids are impatient when it comes to playtime.

Great everyday sneaker
Size: 1 Little Kid, Color: Fuchsia
I bought these for my kid and honestly didn’t expect to like them as much as I do, but they’ve been great so far. They’re lightweight, easy to get on, look cute, fit well, and actually seem comfortable enough that there’s been zero complaining (which is saying a lot). The grip on the bottom is solid, and they’ve held up really well with everyday wear, running around, playground, all of it. I also like that they’re breathable, so no sweaty feet at the end of the day. They’re not the most “fancy” sneaker out there, but for the price, the quality feels really fair. If anything, I wish they came in even more color options because we’d probably buy another pair. Overall, really good everyday shoe. If you just need something reliable, comfortable, and kid-proof, these definitely do the job.
