Top 10 Volumizing Shampoos for Fine Hair in 2025

"Comparing the AJ4 Grey Blue and AJ4 SB Turquoise: In terms of color scheme, both belong to classic colorways. The main difference is that the Turquoise is a collaboration between the AJ series and Nike's own Dunk SB series. The fit leans more towards the snug, supportive feel of a skate shoe, with solid materials and ample padding, especially around the ankle. The heel extension is softer than the regular version, preventing any discomfort, and the sole features a gum rubber patch for better traction. The Grey Blue continues the classic colorway from 12 years ago, making a comeback after all this time. While the materials are standard, they're still of good quality with no major issues. It offers the typical fit and a versatile, classic color scheme. The two shoes have slightly different shapes. For sizing, go with your usual size, but for the Turquoise, it's recommended to go half a size up for a more comfortable fit due to its snugness. Currently, both shoes have stable market prices. The Grey Blue has dropped below retail, making it a good option for personal wear. The Turquoise has seen a price increase, but for those who really like it, it's still worth considering."lg...More

I have to say, AJ4s are just always cool, and I'm totally loving the oxidized green color. The cushioning on the sole is pretty good, thanks to the air unit, so they're comfortable to wear. The design is clean and sharp, with the pure white and turquoise green accents making it simple yet versatile.

The heel features the Jumpman logo, which I think really matches the vibe of these shoes. The sizing is true to size—I usually wear a 38.5, but a 38 fits me just fine without any pinching.lg...More
