  • Lasting insole
    Patent number: 5072528
    Abstract: A lasting insole for a welted shoe. The lasting insole includes: a support layer; a rib for connecting an upper and a welt to the support layer; and connecting structure for connecting the rib to the support layer. The connecting structure is located between the rib and the support layer. Stress encountered during use of the welted shoe is shifted away from the connecting structure. Preferably, the stress is shifted by spaced apart grooves. The grooves are formed by projections which are pressed into the support layer. The projections also facilitate the formation of the rib.
