Rubber heels in Angels Secret Lingerie

Blind Owl

I've submitted a bug report, but thought I'd draw attention to a problem with the shoes in https://www.daz3d.com/angels-secrets-lingerie-and-poses-for-genesis-3-and-8-female-s and find out if anyone else has noticed it and/or found a remedy.

The attached mini-renders illustrate what's wrong. In 'Heels wonky' the character is wearing the shoes included in the Angels Secret set, in 'Heels on straight' she's wearing shoes from another set. The fore-and-aft (to use a sailing term) joint seems solid enough, it's the side-to-side joint that's rubbery.

[ edit/afterthought: in 'wonky' you'll notice that the heels bend in different directions, as if they're magnetized. Removing limits, which I haven't done here, makes it even more apparent. ]
