How long do the insoles take for me to get used to it?
The 3D design of SIDAS insoles may feel awkward at first, as if something is in the way of your feet. It is completely natural to feel this, as it takes time for your feet movement to adapt and correct itself.
However, if you feel acute pain when using the insoles immediately contact our customer service or switch to a different product that better fit your feet.
Is it okay to use the insole on one side only?
Insoles must be used as a complete pair. If you feel discomfort using both sides due to imbalance between the length of your legs, we strongly recommend you switch to custom insoles instead.
How long does it take for the positive effects of the insoles to show?
Going back and forth between wearing insoles and not wearing them may reduce the speed of your recovery. We urge you to wear them on a consistent basis.
What should I do if I’m unsure of my insole size?
As a rule, it is safer to go larger. You may cut the surplus edges of SIDAS insoles to fit the size to your shoes without compromising its effects (refer to DIY insoles fitting for more information.)
There are too many types of insoles to choose from. Where should I begin?
If your feet have especially high or low arches, we recommend the 3Feet range which accommodates for various arches.
For sports such as golf and baseball with a clear objective of using insoles (e.g. stablizing stance), we recommend the 3D line.
For daily use on high heels, loafers and sneakers, we recommend the Flashfit models.
What is the right size to select– my shoe size, or my measured foot size?
Our insoles are designed to match your shoes. Choose your size according to your shoe size.
How durable are SIDAS insoles?
Although the durability varies on the frequency of use, the general product lifecycle of a pair of insoles is two years.
However, since your feet are quick to adapt to new environments and often change shape, we recommend to check with SIDAS every 6 months and switch insoles if necessary, or for further improvement.
