单词	footbed
释义	footbed /ˈfʊtbɛd / noun An insole in a boot or shoe, used for cushioning or to provide a better fit: modern walking boots come with removable footbeds... Made from suede, they boast a cushioned footbed, a slip-resistant sole, and a snug fit. Thanks to the form-fitting footbeds and Vibram outsoles, these backless wonders breeze through pushy terrain. I use custom footbeds in my cycling shoes, but they offer little relief.
