Boots of resistance
The soles of these boots have been sprayed with a fast-drying foam which gives it the texture of a gecko's feet. As a consequence, this means that the wearer is able to walk on walls. They must be able to master the appropriate toe-curling technique which allows them to unstick themselves, such is the adhesive power of these boots. Unfortunately, this means that while trying to walk normally on the ground, they put up a lot of resistance. Therefore, it is difficult to run away, so only the most stubborn heroes insist on wearing them. As it is only for them that the advantage of their power outweighs the great disadvantage of not being able to use it very well.
