"Step into your own personal training facility. Inside, you won't find fluorescent lighting, but you will find unmatched comfort. You won't find preteens waxing a flatbar, but you will find a full-length polyurethane midsole. Needless to say, your feet will never get kicked out. And sure, "train" does rhyme with "pain." But it doesn't have to. Not in the Air Trainer 1, by Nike SB & Polar Skate Co. After all, training is good for the sole."
