Application: For your favorite shoes in sizes 35 - 40½, no trimming is necessary. Simply remove the protective film and stick the insole onto the footbed of the appropriate shoe. The insoles are made from a grippy material with small nubs that prevent slipping, even for sweaty feet. This insole is the right choice for everyday shoes with small heels up to 5.6 cm. Thanks to the soft gel and arch support, you'll feel light on your feet all day long. The cushioning focuses on the ball of the foot and the arch, providing an overall comfortable sensation. The new Scholl GelActiv technology consists of a combination of two types of gel that effectively absorb even the smallest shocks and reduce pressure while walking and running. The firmer gel supports the arch and heel, while the softer gel provides optimal cushioning and shock absorption.
