I have worn this brand of slippers for a few years now.  They are truly the best.  I wear orthotics in my shoes because  I have flat feet and I used to have to have orthotics for slippers too but since I started wearing these, no need.  They mold to your feet and orthotics are not necessary any more.  My feet don't bother me even if I clean for hours.
Even though they're good for people with bad feet, they would be just as good for people who don't have problems.  They may be a little pricey, but in the long run they're worth every penny.
