I came across these fantastic boots on the Crocs website. They are very light and comfortable. Well done by Crocs!
-Synthetic nubuck -Imported -Synthetic sole -Shaft measures approximately 7.5" from arch -200-gram insulation -Faux shearling liner around collar All conditions, any forecast — this boot keeps you warm and dry without weighing you down. It’s waterproof, with sealed seams and a gusseted tongue to keep weather out. You don’t have to worry about getting the synthetic nubuck uppers wet, and the 200-gram insulation keeps you toasty without overheating. Finishing touches include a soft, faux shearling lining around the collar and the all-day cushion of Dual Crocs Comfort™. Tough on weather, light on your feet — that’s the Crocs AllCast II difference
