"washable shoe liners. What could be better? these make summertime shoes so much more comfortable - even heels"
"I put these in a pair of hey dude slides. Other that feeling weird, I didn't notice a difference. I gave them a try for a few hours, but eventually took them out."
"I was hopping to get something so my feet would not sweat when wearing my Crocs. They are soft and cushiony but my feet sweat with them in my shoes."
"This isn't my first order, and certainly won't be my last. They are easy to use and work remarkably well. I use them specifically for Cros because they get loud and lose their ability to remain smell free. Flatsocks takes care of both 100%. The product is exactly what it says it is."
"They are great ! No odors after wearing them with no socks on…"
"I bought several in ‘25 and did so again in ‘26. Nice quality. My feet normally sweat, but i am unaware when these line my shoes."
"I love my flat socks, I wear them with my crocs & no sweat, no smell, and comfy!"
"These are perfection! Cotton, no slip, great feel, cushion but not enough to make the show feel tight. Love!"
"Loving my flat socks. Comfortable & provide the right amount of cushion."
