The Jewel style by Klouds is a comfort based leather slip on shoe with a zip on one side to help with entry and exit. This is part of the Klouds range featuring a "stretch" leather upper. It is neoprene underneath with leather over the top so it looks like a standard leather shoe but has softness and give if you need a wider fit.
These shoes come with a built in arch support. If you have your own orthotics the Klouds innersoles can be removed and replaced with your own orthotics.
