Japanese independent footwear brand Terrem designs products that puts the focus back on footwear. Their latest RAYK model is just that, with a combination of work boot styles on top of a sneaker like outsole. The outsole itself embodies a special construction treatment so that after some time of use a number will appear which correlates to the size of the shoes. Uppers are constructed of Outdry material that is superior in water resistance and breathability. Insole is even more special with the NASA developed Outlast material that retains comfortable temperature that will not get too warm. Brown or black colorways are available matched with crisp white outsoles or beige color with yellow outsole.
