Abstract
An article of footwear includes a sole and an upper. The upper includes a restrictive fabric portion. The restrictive fabric portion includes elastic and restrictive strands. A restrictive-side resistance index is greater than an elastic-side resistance index, when a tensile load is applied to the restrictive fabric portion in a direction of stretching the elastic and restrictive strands, where the restrictive-side resistance index is a ratio of an increase in tensile stress to an increase in rate of stretch of the restrictive strand, in a range in which a rate of stretch of the restrictive fabric portion is greater than a predetermined value, and the elastic-side resistance index is a ratio of an increase in tensile stress to an increase in rate of stretch of the elastic strand, in the range in which the rate of stretch of the restrictive fabric portion is greater than the predetermined value.
