Query: Heel is Too Far back

The shoe has many excellent features as I wrote in my review when I first purchased the boot. However, because the heel is aligned behind the foot rather than under the heel of the foot, the heel of the shoe splayed after only a couple of months of wear. I had to throw them away. It broke my heart for such an expensive item from a reputable company. They were broken and unfixable.
