Abstract
Abstract A ski boot including a substantially rigid outer shell and a flexible inner boot, the inner boot having a tightening strap wrapped around it for tightening the inner boot's rear, arch, instep and ankle portions against the skier's foot. The inner boot has a guide loop at the rear portion and a first fastening device on the ankle portion. A secondary strap, carrying a guide ring at its end adjacent the instep portion, is connected to the tightening strap or the boot itself. The tightening strap is connected at one end to the arch portion of the boot and, after tightening, is fastened, via a second fastening device, to the first fastening device on the boot. From the connection at the arch portion, the tightening strap extends rearwardly, through the guide loop, forwardly around the ankle portion, through the guide ring and then doubles back rearwardly where the fastening devices are connected.
