How does the sizing work for IF/THEN?

The Callisto runs large, especially compared to Nike and Adidas sneaker sizes (some may say those run small). For a great fit, we recommend buying 1/2 size down.

For example, if you're a 10 in Adidas or Nike, buy 9.5 in IF/THEN.

Caring for The Callisto:

We designed The Callisto to be worn day through night and weekday through weekend. Minor scuffs happen, and in our opinion, add welcomed personality. If you prefer a newer looking shoe, here is how we recommend cleaning:

  • Spot clean the upper with a warm damp cloth and the bottom with a little soapy water
  • Deep clean in the washing machine on a gentle cycle with cold water. Remove theinsole prior to washing and air dry only.
