The Flex Runner TD 'Black', launched in March 2019, is designed to provide a comfortable and secure fit for toddlers' feet. Its stretchy design and glove-like fit ensure a soft and snug feel. The neoprene bootie, equipped with dual pull loops, allows for easy changing. Additionally, the mesh construction not only promotes breathability but also reduces the overall weight of the shoe. Enhanced stability is offered through the seam taping over the midfoot, while the toe box is protected by a fused synthetic layer. The soft foam midsole/outsole incorporates flex grooves to provide a natural ride.
