Abstract (en)
Tennis shoes, comprising soles (5) having bases (7) and a large number of horizontal reinforcement crests (9), the horizontal reinforcement crests (9) further comprising ground-contact surfaces (11), toe side wall surfaces (13), and heel side wall surfaces (15), wherein the cross sectional shape of the horizontal reinforcement crests (9) is asymmetric, the tilted angle (θb) of the heel side wall surfaces (15) is larger than the tilted angle (θa) of the toe side wall surfaces (13), a difference therebetween (θb - θa) is 10 to 60 DEG , the height (H) of the horizontal reinforcement crests (9) is 1 to 8 mm, the ratio (L2/L1) of the distance (L2) of the ground-contact surfaces (11) to a distance (L1) of a boundary part between the bases (7) and the horizontal reinforcement crests (9) is 0.2 to 0.8, and the ratio ( mu a/ mu b) of the coefficient of friction ( mu a) of a bottom surface in toe direction to the coefficient of friction ( mu b) in heel direction is 0.3 to 0.9. <IMAGE>
