Sizing across brands only works through the millimetre band, never the number. Easyboot Rx2 and Easyboot Zip both publish in millimetres, so a Easyboot Rx2 4 (hoof length 140 to 150 mm) is matched by finding the Easyboot Zip size that covers the same length.
The Rx2 is a therapy and turnout boot, not a distance riding boot. Its bands are broad, so choose the size that clears a wrap rather than the closest snug number.
The Zip bands are very wide, so several sizes can contain one hoof. It is a stable and recovery boot, not a riding boot; fit it to clear the wrap, not for a close performance fit.
