Abstract
A ski boot of the rear entry type having an upper and a shell base. The upper includes a front portion journalled on the shell base around a first journal and a rear portion journalled on the front portion around a second journal. The front portion of the upper includes two lateral extensions extending from the first journal to the heel of the shell base. A portion of the lateral extensions and/or the second journal engages an abutment on the shell base so as to rigidly link the upper to the shell base when the lower leg of the skier presses rearwardly on the the upper, thereby permitting the shell base to absorb this rearwardly directed force.
