A year and a half ago, or maybe it was two years, I bought a replacement set of what I wear instead of house slippers: Teva sandals, which are more or less a walking/running shoe sole with a minimal arrangement of straps to hold it to your foot. They were a little different from the previous set, but they were on sale.
Unfortunately, I bought the wrong style; worse yet, the seller didn't have half-sizes and I bought the next size down, counting on the remarkable adjustability of the brand's designs to let me center them on my feet. --Except the style I bought didn't have an adjustable back-of-ankle strap. I spent the next year-plus occasionally stubbing my toes, but hey, thirty-dollar footwear. Gotta get your money's worth. A couple of weeks ago, I managed to opened the front door into my right foot, and my little toe caught the brunt of it. It was time for new sandals.
They had about given out anyway (Velcro and even a little cat hair is a high-maintenance combination, especially once the cats figure out they can smooth on it if you leave the instep strap open ). This time, I was careful to order the right Tevas, in the right size. They arrived yesterday and I wasted no time in trying them on. What a difference! Adjustable toe, instep and back-of-ankle straps let me set them to fit my feet, the sole and insole are much better then the old pair, and my toes don't hang over at all. Shopped for price once I'd found the right style, which has put me in a pair with white soles and red straps: I have ambulance feet! But they fit and are comfortable and that's all that counts.
These sandals are the best compromise between barefoot and shod I know of: lightweight, grippy, thick enough to provide protection. I rarely wore shoes and socks at all around the house until I was well-grown (40s) and these are just enough footgear to suit me.
