We offer our Flex Tights in 3 lengths; full, half (to the knee), and 4". Our 4" Flex Tight is designed for runners for any session; track to trail. Made with the beautifully soft FlexSupport, the Flex Tight will give you ultimate freedom of movement, 100% coverage and confidence, and the perfect run. A deep, 10cm waist band feels likes it's almost not there, whilst staying secure from start to finish.
