I’ve worn my heels out on boots that are otherwise in good condition. Can they be replaced without a full resole?

In some cases yes. Certain traditional cobblers will strip the old heel outsole and rebond a new generic piece. In the case of a modern EVA type heel unit it’s important that the layer of material (often a lighter colour) underneath the black outsole is not damaged. These type of repairs are fairly cheap – typically around the £15 to £20 mark. Locally, we would recommend Jacksons in Oldham’s Town Square.
