1 of the 3 New Balance M1906 colourways we checked contain no animal materials, confirmed by both the materials list and the retailer’s own description, plus 2 more that look clean but publish no description to cross-check.
3 animal-free colourways from £90 at Zalando

Checked twice: the EU material label and the retailer’s own description are both clean.

The material label is clean, but no description is published, so a minority material such as a suede overlay can’t be ruled out. Check the photos.
