Technical details, total style. The P448 x Vibram Monalea Drift is made from our next expedition into biobased and sustainable materials. This hiker-style pair features a blue recycled knit design and a navy microfiber wavy trim, accented by an off-white Vibram Natural EVA midsole and a rugged black Vibram Ecostep Natural outsole. The quick-lacing bungee feature and top reinforced eyelet are our version of sport mode.
