I purchased 2 pairs of the Plush Satin Spa Thong in different colors.  I had been trying to find a replacement for Dearforms in the same style, and these are the perfect substitute!  I never go barefoot, so these work great for me, even in the middle of an upstate NY winter.  It may seem unbelievable, but they actually do keep my feet warm, and they are very comfortable, with just the right amount of padding.
