-Breakfast scramble (eggs with whole milk and butter, one gigantic chicken sausage, 3 hearty stalks of asparagus)

The heel heights are very similar -- a little over 1 inch.
Construction seems very solid. The only area where I can foresee some possible early wear-and-tear occuring is on the inner padding around the ankle -- the fabric here is very soft and cushioney.
In terms of size/weight, while the Nikes are larger, they feel only slightly heavier (mainly towards the front of the shoe). The Nikes also have considerably more padding than the Adidas, contributing to the overall size.
