There are many different types of insoles available with varying levels of thickness and arch support. If you are looking for the thinnest possible option, there are some brands that offer very thin insoles that still provide some level of arch support.
One example is the Ideastep insole, which is designed specifically for runners and provides a low-profile, lightweight design with moderate arch support. They are only 2mm thick but still offer targeted arch support and cushioning.
It’s important to keep in mind that the level of support provided by these thinner insoles may not be suitable for everyone, particularly those with more severe foot issues or who require more substantial support. It’s always a good idea to consult with a podiatrist or other healthcare professional before choosing any type of orthotics or insoles.
