Why is the break-in period so important? How long do they take to break-in to my feet?
Due to the design and material of our Z-liners, we recommend giving them a good wear for about 5-7 days. This allows enough time for your feet to start setting in and experiencing the benefits that our insoles provide. Some stiffness in the beginning is perfectly fine and expected, as your feet begin to break in to our footbeds. During this time, support will further be increased throughout your entire foot.
Are they good for flat feet?
Our insoles have a firmer material in the arch region to provide additional support. If you’re looking for support that isn’t too aggressive for flat feet then these should be able to help you. Our material will form to your feet while giving extra stability, especially in the arch region. Being that you’re using them for flat feet, they may take a few days to adjust to as you may feel increased pressure in the arch region.
Do they have arch support?
Yes! Arch support is one of the most important and effective parts. We use a stiffer grade of our material in the arch region. Due to the color and material, it may be hard to see the built-in support in the photos but you can definitely feel it. During the break-in period, our material will begin adjusting to your foot shape, weight and pressure points. The support is increased even more, once they fully set in.
Will these help alleviate plantar fasciitis pains?

How about steel-toe and other types of work boots?

They have arch support built in that will help stability, balance and will leave your feet feeling more refreshed. They’re machine washable and antimicrobial/antibacterial.

We usually recommend replacing the original insole but if your shoes allow for both then you're more than welcome to try both ways to see which you prefer.

For wide sizes up to and including 4E, we recommend ordering one size larger and trimming slightly to fit the tip of the shoe. For widths greater than 4E, we suggest ordering 1.5 sizes larger. This will give you the added area for your feet to properly fit onto our Z-Liners. The tip of our insoles have a border of material that can be easily snipped. Just a pair of scissors will do!
