- High on fashion and comfort, the Clarks™ Kataleyna Glow Boots are an absolute statement-making creation! Perched on a kitten heel and shaped with a pointy toe, the calf-high shoes exude modern elegance and charm. The lustrous upper is made of leather and shows off an eye-catching croc-embossed back panel on the shaft. With the zippered side closure, the shoes can be put on and off easily.
