I've waited a almost a year to write this review because reliability is one of the most important factors for scuba products. These have held up perfectly for many dives and laps in the pool. They are very comfortable, warm, and the raised edge at the rear is very helpful for pulling them on. There is just enough padding on the soles so as not to wreak your feet when walking. I had owned an older pair of Mares that I liked which wore out after several years so I ordered a new pair, but they'd upgraded them with extra rubber reinforcement (much like these), but they were then too wide on the outside for my fins and hurt my feet. These Aqualungs are not as wide and fit well in my fins. There are a few cautions. Most importantly, as some reviewers say, they do run a size too small. I didn't believe and ordered an 11 and had to return them for a 12. Second, they are air tight so they're had to pull off, unless you stick your finger under your foot to a eliminate the vacuum or you use a hole punch to create some holes. Lastly, I haven't found the velcro strap to serve much purpose, the zippers pretty much stay up on their own. Still, these are the best scuba boots I've owned and will buy another pair when these wear out.
