Technology is not only advancing in gadgets like cell phones and laptops, but in the sneaker department too. More specifically, the Asics GEL-Kayano 16.

Because the Japanese shoe manufacturer believes women are more prone to injury because of our structural and hormonal differences, the GEL-Kayano 16 has been specifically designed to delay the onset of muscle fatigue and ease the load on our Achilles tendon – which reduces the risk of potential injury. For those of you who take your running seriously, this shoe increases your running efficiency through its design and 'guide to repeat' system, which encourages the foot to reach its ideal toe-off position.

The most interesting aspect of this shoe, however, is its ability to tell when it's that time of the month. When you have your period your oestrogen levels are high, but the arch of your foot is low, while for the rest of the month your oestrogen levels are low and your arch is high. The GEL-Kayano 16's cushioning design adjusts according to how much support your arch needs throughout the month.

The Asics GEL-Kayano 16 is available in white and gold, as well as white, silver and blue and retails at R1 499. It is available at selected Sportsman's Warehouse, TotalSports and running specialist stores nationwide.
