This invention relates to a sport shoe, which is particularly adapted for ski-running andmountaineering. In consequence of this particular application for the shoe, the principle on which the 5 invention is based involves a heel problem and a metatarsal problem. Hitherto, sport shoes of this kind were shaped mainly from the point of view of the technics of the sport for which they were to serve without giving due regard to the physilO ology of the conditions of movement which arise duringparticipation in the sport concerned.
'I'he technique of ski-running as well as the technique of mountaineering requires heels as low as possible. This requirement calls'for an accordingly low disposition oi' the heel i`nconsequence of which a construction of a sh-last was devised, the rise in the shank portion of which was very small. This necessitates' a shoe whichis very slightly cambered so that the heel must 2 0 extend down deeply into the heel cap in order that it come to bear against the inner sole, `These circumstances are contrary to the anatomic structure of the foot. In the naturally released condition, the fore-foot extends down below the level of the heel.
The problem solved by means of the present 'invention in regard to sport shoes with a view to shaping them at least to some extent in conformity with the ordinary shoes, which are adapted to the anatomic conditions, thus consists in raising the heel and in suspending the middle of the boot from above. This is accomplished by providing the shoe with two superposed instep closures opposite to which a wedge-shaped foot a arch supporter is arranged in the sole which extends from the heel to the metatarsal arch at va.
This boot tends to restore proper conditionsby raising the heel and by suspending the middle -of the boot. The aim is accomplished by providing two separate instep flaps adapted to be tightly spanned in overlapping position-'in inventive cooperation With an extra inserted shoe sole brace IB which curves forwardly and downwardly from 'the heel gradually to disappear under the metatarsal arch. l
In the accompanying drawings two embodiments of. our invention are shown by way of example only in which: Fig. 1 shows a shoe representing a first embodiment as seen from the side with the sole portion broken out and the lacing of the shoe only :halfway effected; Fig. 2 shows aside View of the completely laced 55 shoe;

-,Fig. 6 is a side view of the completely laced shoe.
It is to be realized that the scope of our invention comprehends many equivalent constructions. The-showing of the drawings and the particular description are merely specific exempli- 15 ments and arrangements.
About the region of the instep of the shoe upper a relatively' wide instep cover strip 2 is ctout from the shoe-top longitudinally thereof so as to extend to the metatarsus where it is integral with the remainder or toe-covering portion of the shoe. An interior instep cover strip 3 is arranged parallel withthe exterior instep cover strip 2 and is firmly secured at its forward and lower -end to vthe shoe-top at a point below the integrally connected end of the strip 2 and consists of soft leather, the marginal portions thereof being sewed together with the lateral marginal edges I of the shoe-top I.` On both lateral portions of the shoe-top I string hooks 5 are provided which' are so dmensioned that they arey adapted to accommodate two shoe-strings.
In the ilrstv embodiment of the inventionvas shown lin the Figs. 1 to 3 on the exterior instep cover strip 2, string hooks B aie alsofastened to the edges thereof. However, aslowermost means for receiving the lacing, eyelets l are provided; and as uppermost means for this purpose eyelets 8, which are` situated so far down from the uppermost hooks 5 that with the aid of a shoe string 9 the instep cover strip 2 can be tensioned vigorously, are also provided. This lacing is carried into eiect as follows: At first the shoe-string 9is passed across the interior instep cover strip 3 and through the hooks 5 arranged on the edges 4 of the shoe-top I, then the end portions of this shoe-string 9 are passed through the upper eyelets 8 o f the exterior instep cover strip 2 and tied into an exterior knot, thereby tensioning the exterior instep cover strip 2. The considerable spacing between the edges 4 of the two lateral portions of the shoe-top I permit of pulling these edges vigorouslytoward one another by means of the shoe-string 9, whereupon the soft interior` instep cover strip 3 becomes folded and the shoetop I is caused to bear snugly against the foot.
The second lacing is carried out in such manner that a shoe-string I is passed across the exterior instep cover strip 2 and through the lower eyelets 1 thereof and is then continued through the hooks 6 of the exterior instep cover strip 2 and the hooks 5'of the lateral portions of the shoe-top I. The upper ends of the shoe-string IIJ are passed about the top I and tied together. Finally a leather strap II, which is sewed onto the upper edge of the exterior instep cover strip 2, is tightened and closed by means of a buckle I2. Opposite this lacing a wedge-shaped heel and shank member I 6 is arranged between an intervening sole I4, which overlies the exterior sole I3, and the inner sole I5, as well as the heel and shank piece I1. The wedge-shaped heel and shank member I6 extends from the heel forwardly to the region of the metatarsal arch of the foot, advantageously, to the front end of the metatarsal bones and tapers gradually into a knife edge.
In the region of the heel the thickness of Ithe wedge-shaped heel and shank member I6 is relaf tively great. This member I6 is reinforced by a portion I1 which is, advantageously, somewhat thicker than usual and is prolonged to the end of the wedge-shaped member I6. At the region of the inner marginal portionof the arch of the foot the inserted heel and shank member is, ad-
vantageously, somewhat raised above the corresponding outer side of the' foot arch. With the aid of the wedge-shaped arch supporting member I6, reinforced by the member I1, the foot is held in its natural position on the exterior sole I3 and the heel I8 attached thereto, so as to maintain its natural form and vaulting. Inorder to maintain this form lastingly, the lacings 9, III mentioned above are provided which permit of suspending the middle of the sole and therefore of the foot in its natural form and vaulting from the tensioned exterior cover strip 2 and confine it from above.
In the second embodiment of the invention, as shown in the Figs. 4 to 6, the exterior instep cover strip 2 has no upper eyelets, but an exterior auxiliary string hook 20 which is disposed at the center portion somewhat lower than the pair of uppermost hooks 5 and, that is, in the longitudinal middle plane of this instep cover strip. On each lateral portion of the shoe-top I an eyelet 2I is provided.
When the shoe is to be laced, the shoe string 9 is at rst pulled through the upper eyelets 2| of the shoe-top I'and then passeddownwardly through three lower stringhooks 5 by crossing the interior instep cover strip (the uppermost string hooks of these rows of hooksv string are pulled downwardly, one of these portions being passed from the respective uppermost string hook 5 downwardly about the auxiliary string hook 20, whereupon the two string portions are tied into a knot between the auxiliary string hook 20 and the other uppermost string hook 5.. During this tying operation the exterior instep cover strip 2 is tensioned by tightening the shoe-string correspondingly. In this Way the double lacing is finished and the shoe rmly secured on the foot.
In this manner the exterior instep cover strip can be Well tightened in a beneficial manner with -the very advantageous result that the shoe lits thefoot very closely, while only one shoe-string is necessary for this double lacing.
