The Calma came around during a time in the mid 2000s when Nike released a handful of these super low profile, simple slip-on wmns models. As far as I'm aware these were meant to be versatile, multipurpose shoes designed to be chilled in but also for activities such as yoga. They also somewhat resemble ballet flats. The Nike Kyoto, which released in a handful of variations, also fits in to this category. These feature a pleated cotton forefoot with leather heels. Good condition. See policies before purchase.
