I haven't taken the time to do a good review around here for a while, so here's my contribution to the digital world. You're welcome ;) These shoes are a classic, so they will be around, albeit in different color options, for a long time to come, as opposed to my usual clearance, closeout (or thrifted!) shoe purchases, so hopefully this will help you to make a good choice.
REVIEW OF Vans classic slip-on sneaker:
Size: Vans uses unisex sizing, meaning my 8.5 women's size (or 39 european size) is a size 7, which is essentially a men's size converted to women's sizing (subtract 1.5 sizes from your regular American women's shoe size). Personally, I like that sizing method, because the men's 7 seems to consistently fit me, and men's shoes tend to be a bit wider, which is good for me (more on that next). I would say this shoe is true to size, once you convert to your size. Vans website size charts and shoe boxes do a good job of showing all the size conversions, although I noticed that certain retailers linked to different size charts than what Vans said, especially as far as the European size conversion goes. My shoebox said 7.0 mens, 8.5 women and mentioned size 39 for good measure. All of those sizes are what I normally wear, so I feel their sizing is consistent.
Width: These fit me great, which means they are on the wider side. If your feet run really narrow, you may want to find a similar version by a different company. Vans doesn't offer narrow or wide widths, just medium. For me, the width is very comfortable and doesn't put pressure on the widest part of my foot.
Color: I ordered this gorgeous blush/light pink suede in a woven pattern. I'm completely in love with it. Sadly, this version is virtually sold out everywhere, but there are so many other gorgeous options! There's a perforated suede blush version currently available, as well as a pink fabric version, a silver leather version, a rose gold leather version, a canvas espadrille option... The list goes on. You can see many of the buying options listed below.
Sole: The bottom is rubber, and it's very grippy and practical for everyday wear.
Arch support: The insole liner doesn't have a specific arch support, but my arch felt quite supported as the rest of my foot settled into the cushy liner around it. It looked to me that this insole would come out with a little effort and you could put in your own orthotic if you wanted. The only thing I did notice was that my toes felt a little close to the ground, so perhaps there isn't a ton of padding there? I wasn't uncomfortable exactly, I just noticed I could feel the ground. I'll keep track of how that feels the longer I wear them and update this post. I don't know that I need to adjust the insole at this point, I just noticed it felt different than my other slip on sneakers from another brand.
Quality: My other pair of slip-on sneakers from the brand Dolce Vita retails at over $200 (I bought them new on eBay for $25), so you'd think this $60 Vans pair would feel much lesser in quality. However, I don't feel that way. These are lighter weight, but not in a cheap feeling way, actually in a more comfortable way. I think I will enjoy wearing these more than those other expensive, heavier slip-on sneakers. All the details are very good on the Vans shoe, and I like how the rubber sole wraps up around the upper of the shoe so it should protect the light colored suede from stains and wear. (It's much easier to clean rubber than suede, right?) These feel like a reasonable quality, especially for the reasonable price.
Style: I love this classic, casual style, especially updated with this sweet color and texture. This pair also comes up further on my foot than some other slip-on sneakers, almost to my ankle, which adds to the style (and comfort, actually). That also allows you to wear a sock liner that covers more of the foot without it showing, which is more stylish, in my opinion. The style looks great with cropped pants, and cute summer dresses.
Comfort: As mentioned, these are a lighter weight, which seems to be more comfortable on my foot. The extra bit of width helps the comfort factor as well (at least for those of us with wider feet), and the insole does have some padding to it to add to the comfort level. I wore these without sock liners the first time (I know, I need to get some of those), and didn't get blisters anywhere, although I wasn't walking long distances that day. I will definitely add sock liners and think I could wear these for a long day of walking on a vacation.
Comments: I talked about my other pair of slip-on sneakers earlier, they are designer and I got a great deal on them, and I've worn them a ton, but after trying these classic Vans slip-on sneakers, I think I will just always buy this same style by Vans again and again. Vans has so many style and color options, and they fit my foot so well, I'll just stick with this shoe.
