Poor quality control.

I've purchased several Requisite Goods brand trees (I think six or seven pairs) I thought I'd try a different brand. Sadly, my first experience with SongMics was disappointing. The Heel was cracked on the right insert.

Furthermore, these trees are not true-to-size. I wear 8E Allen Edmonds shoes and I could not get them in most of them. Even when fully compressing the springs.
