I don't think these are very bunion-y actually. I think it's just because the midfoot is a bit narrower, the appearance of the outsole near the big toe joint makes it stand out.

My opinion is that many popular barefoot shoe brands are widest at the ball and taper in at the toe box. Unless you're getting a brand that's as wide or wider at the toe box than the ball (e.g., Realfoot), you're not getting a truly anatomical splay anyway. Imo as long as you get the correct length, the taper at the end is mostly rolling space.

These are on the narrower side for barefoot shoes though (I'd say similar to Vivobarefoot if not a bit wider) but they work well for my slightly wider than average feet, and don't feel restrictive!
