Best shoe inserts for shoes a little big

  1. What are the best shoe inserts, when your shoes slip a little on the heel?

    I have the problem that some of my higher heels will fit perfectly in the summer, as my feet expand, but in the colder weather, they are a tad big?

  2. Aldo has a full-insole insert that makes the shoe about a half size smaller. They are pretty cheap, too.
