They literally thought of everything you need to tie down a kayak and included it. I tried the next one down, the seat has a weird angle for that position so not super comfortable, but I can handle it for 30-60 minutes. My old one can fit up to 4 pairs per tier. I expect years of use. These arrived 6 days before actual delivery date, so that was nice, well packed, it comes with a super case, along with a USB cable and a plug in cable. Comfort and arch support are the most important thing to me when I?m buying shoes and these have both. There is nothing that I don?t like with these Crocks. I put it on and walked downstairs for my husband to see how it looked on me and his response was priceless. Im still getting use to glossy look it has compared to the old ones but thats just me. Although the piping is nice and the connectors are nice the most critical part of a kit like this are the blast gates.
