Well, I needed a new pair of boots for the upcoming winter season, and I saw that these bad boys were only 38 dollars! They're usually around 60ish so it was a steal. As far as sizing goes, I normally wear a 9-9.5, however I ordered a 10 and they fit perfectly! As far as the calves go, yes they are a little tight in the calves, however I mostly own skinny jeans, which is what I wear them with and they are able to fit fine into them. They are a little tighter in the calves than other boots I have, but I am also an athlete so my calves are a little bigger than normal.
I would say if you're debating on buying this product, just do it!
I was fully satisfied with my purchase.
