I just want you to know these are extremely comfortable! Also, they have a very cushy insole which is very important for those of us whose feet aren't what they used to be! I'm 70 yrs. old and have a condition called Fat Atrophy of the Footpad. The fat that cushions our feet is between our skin and our bones. Mine is dwindling which makes walking on a hard surface very painful. It feels like I'm walking on marbles. I found Happy Step insoles for my shoes which help a LOT. However, sandals are a different story. These do the trick. The insole gives enough so my feet are not painful even when I wear these all day. I hope you find this helpful if you have painful feet!
