Frequently Asked Questions
Yes. South Africa uses UK sizing for shoes. SA 9 = UK 9 = EU 43 = US 10 (men) / US 11 (women). Most brands sold at Sportscene, Total Sports, and Woolworths use this system.
Men: US = UK + 1. Women: US = UK + 2. Half sizes follow the same rule. Example: Men's UK 8.5 = US 9.5. Women's UK 5.5 = US 7.5.
UK ≈ EU − 33 for men (UK = EU − 33.5 for women). Use the size chart for exact values since the conversion is not perfectly linear for all sizes.
Stand on paper, trace your foot, measure heel to longest toe. Measure both feet and use the larger one. Measure in the afternoon as feet swell during the day. Allow 1 cm of space in the toe box.
Classic Chuck Taylors run about 1 full size large — size down. If you normally wear UK 9, get UK 8 in Converse. Converse Run Star and other athletic styles fit more normally.
