You don't have to wear shoes to get the ZigTech effect.  Reebok has introduced the ZigNano Sport Sandals, made for the person who wants to be propelled forward with every step while staying comfortable. 

The sole remains low profile while the synthetic upper is comfortable and lightweight.  The forefoot flex grooves to your foot, adding to flexibility while the outsole is made from high abrasion material that is comfortable and durable.

The ZigNanos feature a classic strap that easily slips onto your foot that can be adjusted given the size of your feet.
