The plush-lined snow boots list a PVC outsole, a slip-on opening and five paired size choices. The description also cautions that the sole may crack in very low temperatures and says not to wear it at minus 10°C. Read that limitation before relying on the “waterproof” title or general winter language for your intended route.

Start with foot length, not the insole label

Trace both feet while standing in the socks you expect to wear. Use the longer heel-to-toe result. The listing maps 22–22.5 cm to 36–37, 23–23.5 to 38–39, 24–24.5 to 40–41, 25–25.5 to 42–43, and 26–26.5 to 44–45. Its selector separately prints insole lengths of 23, 24, 25, 26 and 27 cm. Those are two different columns: a 24 cm foot belongs in the 40–41 foot band, while the matching selector says “insole 25cm.” Do not shop as though the printed insole figure were your foot length.

Resolve gaps and volume before ordering

The published foot bands leave half-centimetre gaps between groups, such as 22.5 to 23 cm. If your trace lands in a gap, ask which paired size the seller recommends and request the usable interior length. A plush lining can also reduce space around a thick sock, but the page gives no forefoot width or ankle-opening measurement. Ask for those dimensions and how the two numeric sizes inside a pair differ, rather than assuming the pair is two separate fits.

Choose the route the listing actually supports

Before a cold-weather purchase, compare your expected conditions with the listing’s explicit PVC warning. Its waterproof and anti-slip wording is not accompanied by a test method or rating, so request evidence if water exposure or traction is a deciding factor. The listed Green, Olive Green, White and Orange options do not change the published size map. Confirm your color and paired size together, and choose different footwear for conditions the seller says to avoid.
