Men must wear sandals or flip-flops that expose the top of the foot and ankle bones; women may wear any footwear including closed shoes and socks.
For men, the footwear rules during الإحرام are specific: you must wear footwear that does not cover the top of the foot and leaves the ankle bones (the two protruding bones on each side of the ankle) exposed. Simple sandals, flip-flops, or open-toed slippers are the standard choices. You cannot wear regular shoes, sneakers, boots, socks, or any footwear that covers the ankle or the top of the foot. This ruling comes directly from النبي's instructions about what a muhrim should not wear.
Women in الإحرام have no footwear restrictions. They may wear any comfortable footwear including closed shoes, sneakers, sandals, and socks. Given the extensive walking during الحج, women should prioritize comfort and proper support in their footwear choice.
If a man genuinely cannot find sandals (which is very rare in modern times), النبي (صلى الله عليه وسلم) gave a concession to wear shoes but with the part covering the ankles cut away. In practice, comfortable walking sandals with good grip and support are essential — الحجاج walk extensively on marble and concrete surfaces that can become extremely hot during the day and slippery when wet. Break in your sandals well before the trip to avoid blisters. Many experienced الحجاج recommend sport sandals with a back strap for stability during crowded الطواف.
النبي (صلى الله عليه وسلم) said: 'If one does not find sandals, let him wear leather socks (khuff) but let him cut them below the ankles.'
