First Claim
Patent Images
1. A shoe including a ventilation system, comprising:
- an upper defining at least one opening;
a substantially rigid frame extending along an edge of the opening; and
at least one guiding surface bridging the opening and extending generally outward from a longitudinal axis of the shoe, wherein the guiding surface comprises;
a first end and a second end, the first end and second end integral with the frame; and
a leading edge oriented generally forward of the guiding surface, relative to a heel of the shoe, wherein the guiding surface is adapted to redirect an airflow into the opening under a movement of the shoe.

Abstract
Disclosed is a ventilation system for articles of footwear. The ventilation system includes at least one opening in the shoe upper and at least one guiding surface over the opening. The guiding surface is oriented such that airflow is directed into the opening as the shoe moves. For even greater ventilation, the ventilation system may include a plurality of openings and guiding surfaces. Additionally, a discharge outlet may be included in the sole of the shoe.

32. A shoe comprising:
-
a longitudinal axis; an upper defining at least one opening; and a ventilation system comprising a vane structure comprising; at least one vane bridging the at least one opening, the vane comprising a guiding surface comprising a leading edge, wherein the leading edge is oriented generally forward of the guiding surface, relative to a heel area of the shoe, and wherein the guiding surface extends generally outward from the longitudinal axis so as to redirect an airflow into the at least one opening under a movement of the shoe. - View Dependent Claims (33, 34, 35)
