Flexheel's business idea is to develop a height-adjustable high heel shoe for women. Thanks to a special sole system with interchangeable heels, this shoe can not only change its height, but also its look. This makes Flexheels the perfect high heels for every occasion. One heel can be replaced with another, which can vary in height, design and color, in just one easy step. For example, the Flexheel can be adjusted from 2 to 12 cm in height. This means that the shoe can be worn either as a flat sandal or as a high pump and can be easily adapted to different situations and needs.
