My feet are on the narrow side so it is hard to find slip on shoes/slippers that stay on and the heel doesn't slip. These are pretty darn close, just need to pad them out a bit. The strap is more for loosening the shoe allowing the stretchy upper to expand, you can't really cinch them snug on a narrow foot.The upper is stretchy, so good for bunions, BUT even though they are cushy these really are not good shoes for those with plantar fasciitis, the sole is too flexible. For PF, keep looking. Personally, when I 'm having a flare up, I get the cushiest athletic shoe I can find.NOTE: These are NOT walking shoes. They are fine for light walking, say a trip to the grocery store, or to wear around the house, but that is it.I bought these to use as house shoes as I can never get slippers to fit my narrow feet. Orthofeet makes a slipper that works (and very supportive), but no stock this time of year in my size. These will work great until the moccasins come back in stock. Can't say these shoes are cute, but the fit is close, are comfortable and easy to slide into.Price: Way too high, but I was desperate.
