I was recently sent a sample of PediSpa Intensive Moisturizing Foot Mask. This mask was interesting. Basically it's socks filled with the treatment that you wear, then take off and experience softer skin.
It was a little odd to wear the socks. It felt like I was going to leak, but I didn't. Walking was a challenge, but not impossible. Although it was a little uncomfortably cold at first, the socks warmed up and were fine after that. However, it definitely did leave my feet with a much softer feel - which is a huge plus, especially in the winter when my feet get really dry.
PediSpa can be found at Target for $9.99 for two pairs of socks.
