KOEL Wibi Solid
What is the KOEL Wibi Solid suitable for?
The Wibi Solid is a simple baby rubber boot in bold solid colors – for toddlers who are just beginning to discover the world on their own feet.
First puddles, first pride: The super-soft natural rubber keeps little feet dry while remaining flexible enough to allow babies' feet to move naturally. The non-slip sole provides secure footing on wet surfaces.
Simple and versatile: The solid colors go with any outfit – whether a rain jacket or mud pants. The drawstring at the top of the boot can be tightened to ensure it stays on even during the most energetic play.
Barefoot feeling in rubber boots: The thin, flexible sole with zero drop ensures that little feet can feel the ground. The textile lining made of polyester and cotton is soft and comfortable against the skin.

KOEL Wibi Size Chart
Measure your child's foot while standing from heel to the longest toe and choose the row in which the foot length falls.
| EU Size | Foot length (cm) | Insole (cm) | Width* (cm) |
|---|---|---|---|
| 20 | 11.1–11.6 | 12.8 | 5.4 |
| 21 | 11.7–12.3 | 13.5 | 5.6 |
| 22 | 12.4–13.3 | 14.5 | 6.0 |
| 23 | 13.4–13.9 | 15.1 | 6.1 |
| 24 | 14.0–14.5 | 15.7 | 6.5 |
The foot length includes at least 12 mm of space for walking and growing into – that is why our values are slightly below KOEL's own "ideal foot length".
If your child wears the boots with thick socks, allow a few millimeters more. Measure regularly: If the foot is only 10 mm shorter than the insole, the next pair is due.
* Foot width according to the manufacturer. If your child's foot is wider at its widest point (measured while standing), take one size larger. Dimensions according to the manufacturer.
