Skepticism! Letter with slippers? Open! Suprise! Slippers can breathe and grow, a new knowledge of life for me! Leather very soft and comfortable to wear, slip sole is really ANTI! On parquet, linoleum, tile NO danger of slipping! Super soft supple leather and initially used to well-cushioned sole. Tip my part: Remember what the right and left is, the slipper fits incredibly pleasant to the foot without pressing. Size sizes normal, recommend rather too small than too big to buy, because it still expands. Sensitivity to heat well, with me not (afraid) perspiration. Who wants to have it comfortable and warm is the right place! Value unbeatable!
