I have two pair of Birkenstock sandals from QVC, with the leather tong piece between the toes, I wear sometimes in summer, that I've had for many years, and still look and feel new.
This time of year, I wanted a more closed slip-on shoe, so I bought a pair of Spenco Siesta Solstice clogs (A306913) in navy, wide and they have a really generous toe box, and metatarsal support piece, cork insole that keeps feet from sweating or sliding around. Very easy to just slide on, great colors, all day comfort. I went back for more of this style and QVC currently only has it in M widths, so I read reviews and decided to try a Medium since my feet are average width. It is not as roomy but stays on well, and the toe box is still roomy enough to wiggle my toes and not touch the ends in my normal size. Now my original wides feel baggy but will definitely keep wearing for their uncomparable comfort! Spenco has many other styles in wide or medium to consider, and are less epensive than Birk's, and you don't have to hold the shoe on with your toes as you walk...hate that!
I mention this for you to to know Spenco's are supportive sandals/clogs/shoes something like Birkenstocks support, squarish looking, but most importantly, feel good for your feet.
