"sneakers" originally referred to how quiet the rubber soles were on the ground, in contrast to noisy standard hard leather soled dress shoes. Someone wearing sneakers could "sneak up" on you while someone wearing standards can only stand on you.....此(跑步)鞋有胶底故有落地无声也,相对有皮质底的鞋子是滴答响。所以,此穿上跑步鞋可以静悄悄在你背后,而其他的鞋子(穿者)只能和你并肩而行!!!
追问没看懂,什么意思,说得明白点
