KW (H.A.S) Height Adjustable Spring kits are a great alternative to conventional lowering springs. You are no longer stuck with a fixed lowering height. KW H.A.S. systems allow you to adjust the vehicle ride height with the KW height adjuster even after the kit has been installed. Your vehicle not only gets a more dynamic look, but also the steering behavior and response of the standard dampers becomes more agile. All driver assistance systems and comfort features of a factory adaptive or electronic suspension remain operational and work harmoniously with our vehicle specific spring set up. KW uses high-quality springs made of chrome-silicon steel with spring rates designed specifically for each respective OE suspension damper and wheel load. KW's expertise and engineering ensure the spring rates will pair perfectly with the different damper characteristics of your factory adaptive electronic suspension. Along with the use of high quality materials and the included KW ride height Adjustment - mechanisms, our KW H.A.S. kits always includes the vehicle-specific bump stops with dust protection system to protect your factory suspension against wear & tear caused by road grime and debris. Similar to a coilover suspension, the KW H.A.S kit allow a continuous adjustable ride height within a tested range, something not possible with conventional lowering springs. The dust protection elements and spring perches included in the delivery, when applicable, are always adjusted to the maximum technically possible lowering, typically limited by the factory dampers. With KW height adjustable springs, a sporty and harmonious driving behavior can be achieved without the driving dynamics of performance-oriented vehicles suffering. As with all KW suspension products our engineers develop vehicle specific parameters and spring specifications which undergo comprehensive testing on the Nurburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center.Shipping Notes

So excited for results, feels like it’s working!
Size: Medium, Unit Count: 4
First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful
Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

So so...
Size: Medium, Unit Count: 2
They do what they advertised.
You can NOT walk in them you will stretch them and pop a hole in them.
You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.
