Perfect for a flip flop lover who needs a little more arch support than flip flops usually provide. The strap fits perfectly over my average instep, but I imagine it might be a bit snug for someone with a really high instep. The leather feels supple, however, like it might have some give if it's a wee bit snug over your instep. I
almost always wear a 7.5, and that's what I measure on the measuring contraption in shoe departments. I am returning the 7.5 for a 7. Another thing that I love about these is that I have really long toes, and they weren't even close to hanging off the front
end of these. Yay!
