The EVA slip-on platform sandals list both sole length and suggested foot length. Those are different measurements. Choose from your standing foot length first, then check width and the space the foot has on the platform; do not pick a pair simply because the sole is longer than your foot.

Compare foot length with listed sole length

For 36–37 the page lists a 24 cm sole and a 22.5–23 cm suggested foot; for 38–39, 25 cm sole and 23.5–24 cm foot; for 40–41, 26 cm sole and 24.5–25 cm foot. This implies roughly 1–1.5 cm between each stated foot range and sole length, but it is not a verified usable interior length or toe clearance. Measure both bare feet while standing and use the longer one. If your foot is wide or between the stated ranges, ask for the platform’s widest usable footbed width and a top view with a ruler.

The selector uses the same three foot-length groups. The source names EVA for upper, insole and outsole and a 3–5 cm platform, but does not specify the actual height of each size or any wet-surface grip test. The prose says the fit runs smaller than usual; that is a warning to use measurements rather than a numerical size conversion. A sandal that looks roomy on the sole can still hold the forefoot tightly under the upper, so check both dimensions before ordering.
