I actually have a price alert set on this specific model to notify me whenever it drops to about $38, so I can buy an additional pair if I'm running low (only sneaker I have worn for the past 9 years). Super comfortable. I always keep two new additional boxes in my shoe closet. I get about 18 months of use out of a pair of them outdoors, but that includes all daily activity. I have mild neuropathy in my feet, so I have a "home pair" (usually lasts about 3 years) I wear at home as the compression level is perfect for my feet.
