I wanted another pair of my old Teva Hurricanes but reviewers of the replacement Hurricane xlt said it no longer fit the same. Teva recommended either the Tirra or Zirra as better for a woman's narrow foot. I read that Zirra's strap over the toe is not adjustable so Zirra was out. I ordered the Tirra and while it fits - it's just so clunky looking, i.e., there's so much strap over the foot that I guess I'm going to return them and take my chances with the Terra Hurricane xlt. Honestly. When a company has a winner, why change it?
