The Dr. Scholl's Tired, Achy Feet Soothing & Reviving Foot Mask features innovative self-heating booties that gently warm up to provide immediate relief for tired, achy feet. Infused with Epsom salt, menthol, shea butter, lavender, and peppermint essential oils, these disposable foot masks penetrate deep into foot muscles to soothe discomfort while leaving skin soft and revitalized. The convenient, mess-free design allows you to simply slip on the booties for 30 minutes of therapeutic treatment, making them perfect for unwinding after long days of standing or walking. Customers consistently praise their effectiveness for post-work recovery, with many noting significant relief that extends to the following day, though those with sensitive skin should be aware that the heating sensation can be quite intense.
