Y-3's newest sneaker, the Kaiwa, represents a beautiful confluence of sneaker trends from the last couple years, all combining into one show-stopping sneaker. Y-3 is known for progressive design with technical aesthetics. While the Kaiwa employs that in the sole (which is very chunky, like many pairs that are currently popular), the upper retains the implication of significant quality that comes with a leather paneled sneaker. But the upper isn't totally traditional; it has a sock shape instead of using a tongue. All of these elements could make the sneaker too busy, but it somehow retains a near minimalism.
Pharrell caught some flack for this "Blank Canvas" collection with Adidas, offering white knit versions of everything from the Stan Smith to his signature Running Hu. The problem: They were released as a canvas around the Hindu holiday of Holi, where bright powders are launched into the air to fill the world with color. Whether it was an act of appropriation or reverence is a debate for another time. Either way, the sneakers were a very fresh option and set the scene for popular customization like we'd see later on the Off-White Air Prestos.
The other thing to think about is whether you would like to have a thong style sandal or one that simply crosses over the top of the foot. The thong style gives you the comfort of being able to hold the sandal in place simply because of how the thong goes in between your toes. This will require less straps and securing straps in the rest of the shoe. The majority of cheap price sandals are made without a thong as these are more considered to be used in beach shoes rather than in a proper shoe that can be worn in more formal settings. You will need to decide on how casual your look is to decide if the thong is a look that you can support or it is something that you're going to want to save for when you're headed to the beach.
