Shoe system with interchangeable uppers

A shoe system, said shoe system comprising a shoe, at least one clip, and at least one detachable upper, wherein:

• said shoe comprises a midsole portion, said midsole portion comprising a sidewall surface and at least one elongated channel defined in and extending around said shoe, said elongated channel comprising an opening, said elongated channel configured for receiving said clip in a locking fashion;
• said clip comprises a locking portion for locking within said channel, said clip connecting with said detachable upper via a connection portion, said locking portion is configured for insertion through said opening and into said elongated channel, wherein said locking portion is generally right triangular shaped, comprising a deflectable leg connecting to a fixed leg at a nose, and the fixed leg connecting to an upright at a locking corner, wherein said opening is located between the upright and the deflectable leg;
• and
• said detachable upper comprises an attachment portion for connecting with said connection portion via a connector.

A shoe system, said shoe system comprising a shoe, at least one clip, and at least one detachable upper, wherein:

• said shoe comprises a midsole portion, said midsole portion comprising a sidewall surface and at least one elongated channel defined in and extending along at least a portion of said sidewall surface, said elongated channel comprising an opening, said elongated channel configured for receiving said clip in a locking fashion, wherein said elongated channel is generally right triangular in shape, comprising a base portion, an upwardly extending roof portion and a downwardly extending roof portion, wherein said base portion is oriented along the hypotenuse of said generally right triangular shape, and wherein said opening is defined through an acute corner of said generally right triangular shape;
• said clip comprises a locking portion for locking within said channel, said clip connecting with said detachable upper via a connection portion, said locking portion configured for insertion through said opening and into said elongated channel, wherein said locking portion is generally right triangular shaped, comprising a deflectable leg connecting to a fixed leg at a nose, the fixed leg connecting to an upright at a locking corner, and wherein said opening is located between the upright and the deflectable leg, wherein said deflectable leg is oriented along the hypotenuse of said generally right triangular shape, wherein said deflectable leg is shorter than said fixed leg, and wherein said deflectable leg can be deflected towards the fixed leg when inserted into said opening and when removed from said opening, wherein said connector portion further connects with said upright, wherein said clip can be locked into said channel by inserting said nose through said opening with said deflectable leg adjacent said base, wherein as it is inserted said deflectable leg will deflect towards said fixed leg until the locking corner passes the overhang rim and the locking portion is able to snap into the channel as the deflectable leg is resiliently deflected away from said fixed leg;
• and wherein said clip can be removed from said channel by applying downward pressure on the connector portion thereby moving the fixed leg towards the deflectable leg and allowing the locking corner to be drawn past the overhang rim and through the opening;
• and
• said detachable upper comprises an attachment portion for connecting with said connection portion via a connector.
