Shoe

A shoe comprising:

• a midsole formed of a polymer foam;
• and
• an outsole formed of a thermoplastic elastomer, wherein
• the thermoplastic elastomer forming the outsole includes at least one selected from the group consisting of an olefin-based thermoplastic elastomer (TPO), an urethane-based thermoplastic elastomer (TPU), and a styrene-based thermoplastic elastomer (TPS), and further comprises a matrix and a plurality of domain particles dispersed in the matrix,
• the plurality of domain particles comprise a crosslinked elastomer, and
• the matrix comprises polypropylene,
• the shoe comprises a shoe sole surface comprising a forefoot portion and a heel portion,
• at least one of the forefoot portion and the heel portion comprises:
• a first area with the outsole exposed on the shoe sole surface;
• and a second area with the midsole exposed on the shoe sole surface,
• a portion of the midsole constituting the second area has an apparent density that is higher than an apparent density of the entire midsole,
• the second area has a ground-engaging portion formed of the midsole,
• the first area and the second area are flush with each other when viewed as a cross section along the lengthwise direction of the shoe,
• the outsole and the midsole are heat-fused to each other, and
• the thermoplastic elastomer has a complex viscosity at 140° C. (η140) and a complex viscosity at 180° C. (η180) that satisfy both relational expressions (1) and (2) below:
• 10 kPa·s≤η140≤300 kPa·s (1)
• η180≤100 kPa·s (2)
