Crocs are most notable for their product lines of shoes that are tailored for the summer months. If you need a warm shoe, then Crocs are the best way to go, as they have large holes for ventilation. Among some of the most notable of the brands is the Islander Crocs series. Islander Crocs are an excellent warm weather shoe because of their vented design, and at the same time, they also fit securely to the foot. While most Crocs designs secure the foot with their back strap, the Islander Crocs design has laces that secure the foot for excellent mobility.
