I learned that they have a short life and only buy refurbished units on sale. I cover my cargo with a plastic sheet and then put the net on top. Anyhow, the boat itself is well constructed, with three separate inflated sections, so if a predator were to make a initial attack, the remaining two sections would hopefully keep you afloat until rescue. Very sturdy and high quality metal and finish. My husband even commented it’s so obvious and uncomfortable. They are narrow but l have narrow feet so for me they are very comfortable. Works perfect on my beats. feet that ache and burn from excessive heat and pressure, something commonly experienced by policemen who are on their feet in hot and uncomfortable shoes all the time. Dos and Donts-Do clean your shoes after every wear using a dry soft cloth or magic eraser is required. 👍🏻👍🏻
