The two-strap EVA slides use paired size labels with specific foot-length bands, from 34/35 at 21.5–22.5 cm through 44/45 at 26.6–27.5 cm. Start with a standing measurement; the paired number alone is less useful than the band.

Walk the band boundaries

The intermediate rows are 36/37 at 22.6–23.5 cm, 38/39 at 23.6–24.5 cm, 40/41 at 24.6–25.5 cm and 42/43 at 25.6–26.5 cm. Measure the longer foot from heel to longest toe and include the width across the ball. At a boundary such as 23.5 or 23.6 cm, ask for the actual footbed length and width of both adjacent pairs. A one-millimetre chart break does not account for measurement error or your preferred toe margin.

Check the platform and straps

The source calls upper and outsole EVA, open toe, two straps and platform height 0–3 cm. It does not state whether the straps adjust or how much grip the outsole has. Request strap-opening width, footbed width and a side ruler photo; do not infer shower traction from a bathroom-slipper category label. Black, Gray, Orange, Pink, Khaki, Green and Dark Blue are listed choices.
