I had very high hopes for these slippers however they fell apart in a month and now are just pointless. The pulley is smooth and quiet and the cables seem strong and will last a long time. Hear footsteps. I read the reviews for these slippers and with so many complaining that they were too wide for their feet, I figured that these were the slippers for me. So I do have to block the bottom of it which is inconvenient, but I still like it a lot. Son unos cascos muy falsificados y los vendedores externos se aprovechan para colarlos, por lo que lo mejor es tener cuidado con los vendedores externos, principalmente los que ponga que son de china (CN). Very comfortable and well made. Can feel them through the top almost on the sides. Like them wear all the time, wish they came in different camo colors I was lured by the labelling feature but the velcro strap didnt work out.
