adidas kids sizes
Measure the foot and read the table: the scale tracks EU straight
adidas lists the foot length each size fits: 17.0 cm takes EU 28 (10.5K). Measure against a wall in the evening, read the table, and take the next size if the foot sits on a boundary.
Against Nike, the lengths differ by only a couple of millimetres per size. What parents feel is the last, the shape of the shoe, not the length. If the same child takes different sizes in the two brands, it is usually the width that decided.

Two quick answers
Are adidas and Nike the same size?
Almost: the lengths differ by only a couple of millimetres per EU size. What differs is the last, so the same EU size usually works in both.
What does K mean in adidas kids sizes?
K is the kids scale (9.5K to 13K); after that the youth scale restarts at 1. The EU size runs unbroken through both, so go by that.
