Not to outdo the original Ash Green 4D from Adidas, Taiwanese brand Invincible brought the shoe to the next level. The "Prism" pair is here because the upper sets it apart. Where the OG 4D is remarkable for its sole, these Prisms stand on their own even if they didn’t have a 4D sole. Adidas and Invincible basically hacked the Primeknit process to hide a rainbow of yarns into the knit under a gray outer shell. The result is dynamic and textural. Knit sneakers have been around for a minute, and while they've made advances in textures, this is the best use of color we've seen industry-wide.
Some manufacturers utilize sandals that are made from a combination of materials. This tends to be a man-made material for the soles along with fabric for the straps. The fabric straps can be quite comfortable as they will breathe a little better than leather will when it is hot outside. The other great benefit you will receive when you have sandals made from man-made materials is the ability to simply chuck them into the wash whenever they start to stink. After all, it is hot outside and you will be sweating in your cute sandals. Having something that you can easily wash will give you the comfort of being able to wear your cute sandals a little more often throughout the summer. You may find that with this ease of maintenance that you wear them more often.
