CA 2012140

An athletic shoe formed of a sole, an upper attached to the sole and including an ankle portion extending around the medial and lateral malleoli, and an inflatable bladder attached within the ankle portion. The inflatable bladder has a medial section and a lateral section, with an inlet mechanism for supplying pressurized gas to the interior of the bladder. Weld lines divide the medial and lateral sections into upper and lower portions and prevent the formation of restrictive vertical columns of pressurized gas in the medial and lateral sections.

Une chaussure athlétique formée d'une semelle, d'une tige fixée à la semelle et comprenant une partie cheville s'étendant autour des malléoles interne et externe, et un sac gonflable fixé à l'intérieur de la partie cheville. Le sac gonflable a une section médiale et une section latérale, avec un mécanisme d'admission pour amener du gaz sous pression à l'intérieur du sac gonflable. Des lignes de soudure divisent les sections médiale et latérale en parties supérieure et inférieure et empêchent la formation de colonnes verticales restrictives de gaz sous pression dans les sections médiale et latérale.
