I’m usually not a fan of slip on shoes for anyone (male or female) having a wide foot and a high arch.
Clark’s Un.Seal is an exception. The vamp is long and the elastic insets are minimal. The toe-box is wide but not so deep that you can pinch excess leather in the toe-box area. This person is also wearing men’s 3/4 Superfeet insoles for added support and comfort.
This shoe would not work for someone having a narrow foot with a high arch, or a narrow foot with a flat arch. Those foot types would swim in this shoe.
However, if your foot looks like the foot above, then this a perfect leather, casual shoe for you. You can dress up jeans or Khaki’s with this shoe and you’ll always look great.
