Our magnetic stirrups always contain the same magnets, but the magnetic strength can be varied by choosing a different insole model as follows:
STANDARD insoles come with our magnetic safety stirrups by default. They offer just the right magnetic power for most cases: Your stirrups stay at your feet while riding, but still allow you to release them with a simple motion. The vast majority of our customers - over 95% - are perfectly happy with this version.
PLUS insoles are for those who need (or want) a little more adhesion. We usually recommend them to professional riders as well as para riders. They also work great for boots with thicker soles, to balance out the loss in magnetic power that comes with thicker shoe soles. Note that the PLUS version is ca. 6mm thick, which is 1mm more than the STANDARD version.
Both versions release in case of a fall.
