Part 2 asks viewers to look beyond the size printed on a shoe. Chris Duffin and Dr. Ray McClanahan use a removable liner to compare the foot with the available space, drawing attention to the shape of the toe area.
The discussion includes checking fit with toe spacers on if they will be worn inside the shoe, as well as the relationship between the liner, the upper and shoe volume. The speakers also connect toe-box space with their strength-training perspective.
The closing message is to allow time for adaptation. This is a discussion of their fitting approach, not a promise that feet will reshape or performance will improve, and it should not be read as encouragement to switch immediately into demanding training in unfamiliar footwear.
