The AEM 21-781DS Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Mercedes Benz CLA250 models. Air enters the system from the factory fresh air inlets, through replacement air ducts and into a roto-molded, aerodynamic AEM air box containing an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. This air intake system was developed to accommodate the engine's factory emissions control devices including the ECU. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Great shoes!
Size: 5 Big Kid, Color: Light Grass Green
This is my second time purchasing these shoes!
Not only are they stylish and well made, but they are comfortable! These have been used as running shoes, they have great support and suitable for long distances. The fit is true to size.
Thank you!

Shoe laces aren't great.
Size: 3 Big Kid, Color: Black White
I bought these RUNSIDE kids tennis shoes for everyday wear and school, and overall they’re lightweight, breathable, and comfortable for active use. My child liked how easy they were to put on, and they worked well for running and general play.
The shoes themselves feel flexible and pretty comfortable for the price point. The upper material is breathable, which helps during sports or warmer weather, and they don’t feel heavy on the feet.
However, the main issue is the original shoelaces. They constantly came untied no matter how they were tied, which became frustrating pretty quickly during the day. We ended up replacing them with better-quality laces, and that solved the problem.
Pros:
* Lightweight and comfortable for kids
* Breathable material works well for active use
* Easy for everyday wear and school
* Good fit for the price
Cons:
* Original shoelaces do not stay tied well
* Laces needed to be replaced for practical use
Overall, these are solid budget-friendly kids’ sneakers that work well once the laces are swapped out. The shoe itself is comfortable and functional, but the included laces are definitely a weak point.

Great shoes
Size: 8 Toddler, Color: Camouflage Gray
Bought these for my three-year-old son, they fit great and they are easy for him to slide on himself. The laces seem to come untied a lot, but otherwise we love them!

Perfect for Active Kids
Size: 4 Big Kid, Color: Black, Size: 4 Big Kid, Color: Black
My son loves these shoes. He says they’re really comfortable and lightweight, and he can run and play in them easily. So far they’ve held up well. He can fit them. Non Velcro and slip resistant.

Good, but not great! Insert kept falling out.
Size: 3 Big Kid, Color: Black
I bought these for my 8 year old and the insert was loose and had to be played with multiple times before I could get it to stay in place. I eventually had to place a double sided sticky pad to get the insert to stay.
