text: As always, Propet slip-ons are great shoes. It is the only type and brand of shoe I have purchased for more than 12 years. Number of shoe pairs purchased in that time is roughly 8-10. The soles last at least 12 months and in some cases 2-3 years and I wear these every day. I am not a shoe &#34;collector&#34;. I have one pair for winters in western New York (over 10 years), one pair for every day, and two pairs of old ones I use for lawn work. Just purchased a fresh pair and expect to get 12-36 months out of them.
