I noticed that the insoles on the SF model had like a forest or something on them. Maybe some kind of special edition.
Yeah. The wording on the description is slightly different too. The SF says: "A fabric and synthetic upper provides more stretch for a second-skin-like feel." The regular one says: "Lightweight, single layer mesh in the upper provides more stretch to feel like a second skin."
But that doesn't seem like much of a difference. Ha
