Also toe = Schuhspitze? Ehrlich?
Well, yes. I'd say so.
c : the forepart of something worn on the foot
the toe of a boot
That's what they call it in a shoe store, for example. It could be that Schuhspitze is more limited, that is, only includes the very front material of a shoe and not anything else, but there is at least some overlap.
Personally, I've never heard of 'toecap' before. It could be BE, but if I were to guess its meaning w/o any context, it sounds to me like some external thing attached to the outside of a shoe in the front for added protection or something like that.
