The high-top knit item is titled “sneaker socks,” while its specifications call it slip-on casual shoes with a mesh upper, EVA insole and rubber outsole. Confirm it is the pictured footwear, not a separate sock product, before relying on the size chart.

Walk the chart without converting blindly

Foot-length labels run size 39 at 24.5 cm through size 46 at 28.0 cm in 0.5 cm steps. Measure both feet standing at day’s end, use the longer, then locate the corresponding listed length. This chart labels foot length rather than shoe interior length; ask for the latter and forefoot width if your foot is broad or between listed lengths. Do not assume another brand’s EU 42 has the same internal last.

Confirm construction and stock

Black Gray, Black Full and White Gray are selectable. Request a current photo showing the toe, flexible knit collar, outsole and pair together, plus the selected size and colour. The source’s “lighted” feature tag is unexplained; do not assume illumination or a power component from that word. The listing also says the pair arrives without a box. The shoe-size guide provides a broader chart-reading example.
