A pair of tights restrains the knees from wobbling motions, stabilize running motions, and can be comfortably worn for a long time without causing fatigue. The pair of tights includes front parts for covering the front side of the body between the waistline and the front sides of the ankles, back parts for covering the back side of the body between the waist and the back sides of the ankles, outer side parts each covering a side region between the greater trochanter and the outer side of the ankle, back waist projections each formed integrally with the outer side part and projecting from the upper end of the outer side part over the back side of the waist, inner side parts each covering a region between the crotch and the inner side of the ankle, outer knee support parts for supporting the outer side of the knee, inner knee support parts each for supporting the inner side of the knee, and sartorius and adductors support parts each covering the back side of the waist, the sartorius and the adductors, and extending to the upper end of the inner knee support part. The outer side parts, the back waist projections, and the outer and inner support parts are formed of a stretchable material having a high elastic modulus higher than that of a material forming the rest.
