Ayers, Watertown, MassL, assignor to Brown Company, Berlin, N; H., a, corporation t of Maine Application March 29, 1939," s rial No.2643194 5 Claims. invention relates to a multi-ply counter which possesses such firmness or rigidity as is desired in its walls and yet affords such high flexibility or softness as is desired at certain of its edge portions.

The counter hereof comprises at least three differently-sized, superposed, bonded, counter blanksor plies, including outer plies of relatively flexible material and an inner ply of relatively stiif material. The inner-ply blank is smallest- ,"SiZGd and occurs between an intermediate-sized,

outer-ply blank, whose upper and side marginal "portions project beyond the upper and side mare ginal portions of the inner-ply blank, and the. largest-sized, outer ply blank, whose upper and side marginal portions project beyond the upper and side marginal portions of the intermediatesized, outer-plyblank. The inner-ply blank, be-

ing of relatively stiff material, plays the roleoi a stiffening corein the counter. I The largest-sized, outer-ply blank, being relatively flexible or soft, furnishes in the counter such edge portions as bespeak comfort to the foot.

The three blanks or plies .of the counter all have lower edge portions in substantial coincidence at the front terminal regions 3 of the heel flange, since the recess or opening 0 in each of the blanks Ill and H2 is somewhatshorter thanthe length of the lower edge portion of the blank l l.
