This is the Guidi-795z, lined reverse stag leather lace up boot in size 45. As is common knowledge, Guidi fits small, and these fit just enough smaller than my backzips so as to be uncomfortable. I'd estimate best for a true size 10. I purchased them new, and wore them out twice, and rate them an easy 9/10. The reverse stag leather is buttery soft, totally different than something like their reverse horse. I'll ship for free in the US.
