Iridescence on its own is unstable as a design, which is why the Pulse Aqua here matters: it fixes a colour the shifting finish can be measured against. The upper is Cloud White leather with a treatment that throws off blues and greens as the angle changes, and the aqua trim sits in the details, close enough in family to look intentional rather than pasted on. Leather takes the coating differently than synthetic does, holding it slightly deeper and with less plastic sheen.
It went on sale on 12 September 2021 at 80 dollars, in the junior size run rather than the toddler one. Everything structural survives the scale-down: a band across the collar, the crossed side panel that anchors it, and a cupsole lifted at the rear, which are the parts that have identified a Forum since the model's 1984 debut. Special finishes appear far more often in kids sizes than in adult ones, because the material cost of the treatment is lower on a smaller upper and children tend to pick a shoe on how it looks rather than what it is made of.
