Lightweight, comfortable, and elevated design!
Size: 7, Color: Grey
Ordered these for an upcoming trip to Italy where we will need to travel light so I wanted something I could push together in a suitcase where it might get squished - and I didn't want to do that with my expensive loafers/dress shoes.
These turned out to be the PERFECT choice - they are great shoes which fit true to size, feel light and pack extremely well, look dressy enough for dinner or the opera, but are still good to walk around in no matter what kind of streets we are walking on (Cobblestones and all, since places like Florence and Roma are ancient). They have a nice flexible upper and breathable knit which makes them light feeling on your feet too, they lace up nicely and stay tied, which is great, and they are just overall very comfortable shoes. I would have liked maybe a little more in the way of arch support since I have weak arches and that can be a problem for me when walking a lot...but I wore these as a trial beforehand just to make sure and no issues walking in them for well over a mile during a nice evening stroll post dinner. The inside does have a molded foam insert, so that's why I didn't take a star off for this - they might not have super high arch molds, but they are still very, VERY comfortable.
These truly do look like an oxford but feel like a sneaker, making them a great "go to" shoe for pretty much anything - you can wear these to work and then to go get chicken wings and watch sports at a bar and they fit in seamlessly in BOTH places, LOL. They look great with jeans or khakis, which is a plus. Note that I don't think these look dressy enough to wear to say, a wedding or something super formal, but that's only because they are knit and unless it's a casual wedding or at the beach, it's probably a little too unstated.
If packing these for a trip, know that you can put them in your suitcase for a long time and they pop right back up to looking like regular shoes without wrinkles or weird creases, and without ruining the shape. So they are great for a weekend trip where you really don't want to bring anything extra.
I got the gray pair and they are a nice in-between color that you can wear with anything. The black pair might seem a little more formal and dressier, but these are certainly no slouch, so if you aren't sure which color to get, the gray is a great choice.
And then there's the price. You cannot find shoes in this style which are hybrid work/play shoes for $32 these days, especially not new, even if you try your luck at the Nordstrom Rack or somewhere like that. You definitely won't find ones this nice and elevated looking either at a big box store - even Walmart charges for similar ones and they aren't nearly as nice. So these are a great value for the price and they should give you a lot of mileage for what is really not a lot of money. Time will tell how long they last but if they can survive the cobblestone streets of Italy for 3 weeks then they can probably make it through anything LOL. I will update this review accordingly after the trip and advise!
Highly recommend these if you need a dress shoe that's not stuffy so you can wear it with anything, or for a trip where you can't reasonably fit more than one pair of shoes, etc. They give you a great bang for your buck - you can't go wrong with them!!
