* All measurements are in inches. Measure your bare foot for best accuracy.
* Boots run true‑to‑size. If you wear half‑size, we recommend sizing up for thick socks.
* Natural rubber will soften and break‑in with wear; insole is removable for orthotics inserts.
* Actual fit may slightly vary across boot styles.
