ASICS GEL-FIT SANA Women's Training Shoes The GEL-Fit SanaTM features a Flexible Fit system with flexible support bands from heel to forefoot, to provide adaptable support in designated areas. Designed with a stretchable mesh upper and MONO-SOCK® upper construction, it gives a sock-like fit and feel that makes for a secured comfortable wear. A smooth inner lining and lightweight, low-profile midsole gives this GEL-Fit SanaTM a barefoot-like sensation and an overall customized fit. The Gel-Fit Sana Women's Training Shoe from Asics is made from a Mono-Sock Fit System. This feature has been specifically chosen because it is an elasticated internal sleeve which replaces the traditional shoe tongue and sits closely and comfortably against the foot to offer a sock-like fit. A Pull-Loop has been fitted to the heel of the shoe, making it easier to put the shoe on as well as taking it off to save time and effort that could be put into your training session. Gel Technology has been added in the rearfoot of the shoe which helps to attenuate shock during the impact phase as well as allowing for a smoother transition through the foots natural roll to midstance. The Rearfoot Gel System also offers much needed cushioning under the rearfoot, keeping the foot comfortable for longer. AHAR PLUS Rubber has been chosen to construct the outsole of the Gel-Fit Sana. This is because the rubber when placed in critical areas of the outsole can offer much needed durability as it is a compound that is 50% more durable than standard high abrasion Asics.
