Sperry Top-Sider is targeting the fitness market with new women’s performance shoes. The Son-R Flex line, debuting for spring ’15, includes a packable slip-on flat created for the yoga enthusiast or the customer with an active lifestyle. The shoe features the brand’s patented Son-R technology with an interactive footbed designed to provide sensory feedback for greater stability and agility. Adaptive siping on the outsole disperses water for use on wet or dry surfaces. Priced at $85, the Son-R Flex style is offered in seven different colorways and will deliver in February to better lifestyle and active/outdoor accounts. The shoes will also sell in Sperry Top-Sider branded stores and on its e-commerce site.
