These are surprisingly moisturising for the price; a lot of foot masks are way more expensive than this. I used it after a hot bath and after I'd scrubbed my feet, so maybe that heightened the hydration effects. I knew that I had to stay relatively still whilst using them, but I only shifted my toes a little bit and the plastic outer wrapping ripped open. :( I had to hop to the kitchen and grab a plastic bag to wrap over my feet! Like any skin mask, the effect only lasts a couple of days at maximum, so I think with regular use these would be pretty good (and better than using the heavy, thick foot creams that take forever to absorb!).
