Thank you for your inquiry. The difference between our insoles is the shape of them; besides that they are constructed of the same materials. The "casual" shoes fit our Hubbard Free, Get Up Lace Up, Getaway, and Boot-Up models. The "go to work" insoles fit our Founder, Market Cap, Tipping Point, Frequent Traveler, 24 Seven, Ivy Legend, Highlander, Bucks and City Legend models.
