An article of apparel, comprising: a garment structure (1200; 1300; 1500) for a human foot, wherein the garment structure includes one or more fabric elements, and wherein the garment structure is structured and arranged so as to provide a close fit to at least an arch area of a wearer's foot; and a foot position feedback system (1202; 1302; 1502) integrally formed in the garment structure, wherein the foot position feedback system includes: a first region (1206; 1308; 1504) that extends across the arch portion from a medial side of the garment structure, across a footbed portion of the garment structure, and to a lateral side of the garment structure, wherein the first region has a first compressive force application capability, and wherein the first compressive force application capability is higher than a compressive force application capability of the fabric element making up a largest proportion of the garment structure, and a second region (1208; 1306; 1504) that extends across the arch portion and is at least partially surrounded by the first region, wherein the second region has a second compressive force application capability that is different from the first compressive force application capability, and wherein the second compressive force application capability is higher than the compressive force application capability of the fabric element making up the largest proportion of the garment structure. a garment structure (1200; 1300; 1500) for a human foot, wherein the garment structure includes one or more fabric elements, and wherein the garment structure is structured and arranged so as to provide a close fit to at least an arch area of a wearer's foot; and a foot position feedback system (1202; 1302; 1502) integrally formed in the garment structure, wherein the foot position feedback system includes: a first region (1206; 1308; 1504) that extends across the arch portion from a medial side of the garment structure, across a footbed portion of the garment structure, and to a lateral side of the garment structure, wherein the first region has a first compressive force application capability, and wherein the first compressive force application capability is higher than a compressive force application capability of the fabric element making up a largest proportion of the garment structure, and a second region (1208; 1306; 1504) that extends across the arch portion and is at least partially surrounded by the first region, wherein the second region has a second compressive force application capability that is different from the first compressive force application capability, and wherein the second compressive force application capability is higher than the compressive force application capability of the fabric element making up the largest proportion of the garment structure. a first region (1206; 1308; 1504) that extends across the arch portion from a medial side of the garment structure, across a footbed portion of the garment structure, and to a lateral side of the garment structure, wherein the first region has a first compressive force application capability, and wherein the first compressive force application capability is higher than a compressive force application capability of the fabric element making up a largest proportion of the garment structure, and a second region (1208; 1306; 1504) that extends across the arch portion and is at least partially surrounded by the first region, wherein the second region has a second compressive force application capability that is different from the first compressive force application capability, and wherein the second compressive force application capability is higher than the compressive force application capability of the fabric element making up the largest proportion of the garment structure.
