These fit very nicely, are comfortable, and work for my wide feet!
Size: 12 Wide, Color: Brown
Once I learned while shoe shopping in my youth that I needed wide-sized shoes, I wasn't able to easily choose from any shoes I saw in the store. I usually have to go find the wide widths and have to deal with the limited styles they have. Shopping online has been hit and miss, too. Sometimes, shoes are advertised as wide width, but end up still being too narrow. These shoes fit me just right. They were not too tight at the toes, gave good width at the arch, and the opening was large enough that I didn't have to undo every single lace just to get my foot in. They also look nice, and I'm sure will take a decent polish. Also, note that this does say it's an Oxford shoe, but it does have the open lacing and is more of a derby-style shoe. This also helps with sizing for my wide feet. If I didn't already have a pair of black shoes, I'd look at picking one of these up. My only reservation with these is that the soles are not dark-colored to complement a more formal style. I feel the white makes them a little more casual. The sole is also more transparent/opaque coloring at the heel and underneath, which you can kind of see-through, so keep that in mind. It's not fully clear, but is kind of transparent, which I was not expecting. I think it also shows where it picks up dirt as you wear it. Just more of a style cue one way or another. As a reference, I buy the 4E wide and Extra Wides in New Balance and Skechers. I also have a hard time getting any good fit in Nike shoes.

The quality is excellent for the price
Size: 10, Color: Silver-pu
I am absolutely in love with these DREAM PAIRS double bowknot heels—they are stunning, elegant, and even more beautiful in person! From the moment I opened the box, I could tell these shoes were going to be a showstopper. The double bow design is so feminine and eye-catching, and the added crystal rhinestone detailing gives just the right touch of sparkle without being over the top. The open square toe is super flattering and modern, and it gives the shoe a stylish, high-end look. The ankle strap adds extra stability and keeps the heel secure while walking, dancing, or standing for long periods. It fastens comfortably without digging into the skin, and the buckle feels sturdy and well made. The heel height is perfect—high enough to elongate the legs and give that confident, dressed-up vibe, but surprisingly comfortable to walk in. The insole has a nice cushion that makes them easier to wear for parties, weddings, or nights out without feeling like your feet are dying by the end of the night. I wore these to an event and got endless compliments—everyone thought they were designer! They photograph beautifully and add a glamorous touch to any outfit, whether you're wearing a dress, jumpsuit, or even tailored pants. The quality is excellent for the price—the materials feel durable, the craftsmanship is clean, and nothing looks cheap or flimsy. The bows hold their shape perfectly and the stones stay secure without falling off.
