ASICS BLADE FF Asics BLADE™ FF men’s indoor trainers help to create good support and flexibility especially for squash and badminton players, where effective multi-directional movements are critical to your success. The upper is redesigned to better hug the foot and to provide improved support. Another new feature are lightweight film reinforcements with a minimalist character that are lighter than traditional reinforcements. The heel-toe difference, where the heel is slightly raised, helps for a faster start. This makes moving from the baseline to the net easier and faster. The shoe features X GUIDANCE™ technology that promotes better court coverage. This makes it more flexible and easier to move around the court. ASICS BLADE FF
