Firstly I have had several of these Billfish models over the years as well as a few other Sperry boats. I mainly use them for hiking, a lot of hiking, on the Jersey Shore, in Florida and in Canada in the winter. Hiking on sidewalks, sand paths, gravel paths, you name it. I weigh over 300 pounds and don't wear good shoes. I read other people's reviews here and want to make sure readers know I'm reviewing the Billfish 3-Eye Boat Shoe and not the ultra-lightweight version or classic pumps with minimal soles and leather laces. I've experimented with different sizes for years. I have three closets full of shoes and they are a reliable size 11D. Except for Sperry. They come small. This is not just my experience, it reflects the experience of many people I know who have. On the other hand, the leather upper stretches over time. For example, I bought a size "11.5 M" at Revain. The sizing info provided by Revain is confusing but I think that size marking printed on the tongue is 11.5D. It fits like a glove. Literally. I have to trim my toenails when I wear them and they need some stretching on my toes but they will be fine. They are exactly the same size as my last pair and fit barefoot. When I have a sock other than a thin thin one, the shoes are uncomfortable - maybe they'll get better over time, but for now they're only for bare feet. So I decided to order a different size. Revain didn't stock a selection so I found another site where they sold me a pair that were listed as '11.5E' but '11.5W' is what is printed on the tongue (W stands for 'wide' in Sperry jargon). . They are more comfortable and the ones I will wear when I put my socks on. I was tempted to order a 12D model, thinking that such a wide size 12 might be 11.5W wide, but I'm glad I didn't. them in the program. Provided they have the desired dimensions. They stretch but shouldn't hurt the first time you wear them. 2) Draft. I chose the Billfish 3-Eye because I wanted something more versatile than classic pumps. I love the soft soles - when I switch to classic quarter-inch rubber-soled pumps, I miss the feel of it. I like ventilation on the sides as it gets hot on my feet (even in winter I like ventilation). I like the padded tongue - some shoes can hurt the back of my foot after long walks. The laces feel unbreakable - unlike the leather laces on classic pumps, which look great but always come loose or break. As far as "arch support" goes, my feet are pretty flat and I can't find a shoe that offers arch support that comfortable. I wear them a lot and they are comfortable for me. The support they offer is probably minimal but goes beyond the non-existent support of the classic Sperry boot.3) Quality. The shoes I've bought from Revain are made in the Dominican Republic and the ones I've bought elsewhere are made in Vietnam. The construction is the same, although the Dominican shows very little color variation in the skin patches - this can only be seen up close in good light. These shoes have a "glued" sole and not a sewn-on sole like classic pumps. Some reviewers say the outsole separated from the upper early on. I've had shoes that do that, but never with the Sperry Billfish, which I've owned and used over the years. They actually held up very well - by "support" I mean I wore them until the material frayed in the heel area exposing the insole, and then finally frayed exposing the heel to the board. I walk a lot and don't wear good shoes. Sometimes, when I'm too lazy, I kick off my heels and wear them as slippers to go to the post office - easy to put on, uncomfortable, but the shoes survive with no sign of wear and tear. So finally, make sure this is the model you want, choose the right size for you and you won't be disappointed. If it suddenly falls apart (which has never happened to me with Billfish), complain often and violently, even if the return period has expired. It's the only way companies can know if something they use or do needs improvement.
