Very pleased with these!
Size: 9, Color: Egret/Lavender/Multi
I wasn't sure about these, but have had good luck with other HEYDUDE shoes. So I ordered these. True to size. I'm pleasantly surprised. Very comfortable and cute. They don't look like the usual HEYDUDE frumpy shoes. But yet they provide the same comfort as frumpy HEYDUDES. (Nothing against frumpy HEYDUDES. I own a pair and wear them for comfort.)

Runs large and too squishy of a sole
Size: 9, Color: Black/White
Why did you pick this product vs others?: I really wanted to love these, but the fit was off, and the sole is extremely squishy, which on a platform shoe was nearly a disaster.  I wear an 8.5/9 in all my shoes. I got a size 9, and they were far too big. I also have wide feet and the straps still had excess room between the strap and the tops of my feet.  I tried the shoes on, took a few steps, and the sole was so squishy it felt like I was falling. If I had a size 8, instead of 9, maybe that would not have happened.  I ended up returning, but wish the fit was better as these are super cute shoes

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.
