Klas & Sylph offers three different levels of arch support that are compatible with three different types of foot. We generally recommend low arch support for flat feet, medium arch support for normal feet, and high arch support for high-arch feet. This, however, does not mean that you cannot wear different levels of arch support. In fact, some of our flat-footed customers prefer medium arch support to low arch support, and some of our normal-footed customers find greater comfort in low arch support instead of medium arch support. Please see our complete list of arch support recommendations on our Health Benefits page.
Please note that if you have never been accustomed to arch support as foot health solutions before, it could take up to 3-4 weeks for your feet to properly adjust to the arch support. For smoother and more comfortable transition, we advise you to start wearing our sandals for a short period of time before gradually increasing your wear duration over time.
