Columbia Tillie Creek Sandal - Grillazul 13 . Challenging summer water sports demand high-performing sandals and the Tillie Creek delivers. Designed for on-the-go athletes it provides the perfect balance of cushioning stability and support to keep you moving when things in the water get wild. 3D Techlite in the heel provides a fit that goes beyond traditional straps and webbing - this incredible material conforms to provide maximum comfort. The footbed has slightly softer Techlite on top and a more rigid version underneath for a balance of cushion and stability. Speed laces over the upper lets you lock things down on the fly without the hassle of traditional water-absorbing lacing systems. The perforated neoprene frame enhances fit and water resiliency while an internal TPU shank provides extra support and rigidity to protect feet.
