Synthetic/Textile Drain Tech – These shoes have a unique design feature that allows water to simply drain through them, thus making for the ideal shoe to wear at the beach. EZ Slide – Feature that allows the foot to easily slide in and out of the shoe without socks, thanks to the shoe’s utilization of fabrics and synthetic materails. Synthetic upper – Few people who want activewear toe shoes want leather, and it’s because synthetic is stronger, waterproof, and will ultimately stay a whole lot cooler on the foot. Two fasteners – These Fila shoes are actually ideal for running, not only for beach-wear, and so they have a strong bungee fastener along the top, but also an adjustable fastener on the back for improved stability, comfort, and non-slip protection. Four-way stretch fabric – This beneficial feature of the Fila toe shoes means that the foot is actually cradled by stretchable fabric and mesh, not relying entirely on the synthetic upper, which creates a lot more strength and durability for long-term wear.
