I suggest that the hissy fit is more about something else than about the boots. The boots just became a way for him to express his anger. I'd ask him what he's really upset about.
To me, this sounds more like a communication problem. Sounds like you were trying to be kind by going along with his choice of buying boots. I suggest that you were feeling irritated about him wanting to buy you boots and he picked up on this, probably sub-consciously. Both of you were unaware of what was happening.
I'd have reminded him that I didn't want the boots but have other things on my wish list. Perhaps asking him why he was focused on boots could've cleared up the situation. Did you write down a list for him? If your list was just verbal he may have forgotten what was on it.
If this is just one more time that the two of you have had communication difficulties, I suggest getting the book, Non-violent Communication. There is also a web site that will give you an idea of how to word things so that they are more easily heard. This form of communication takes the emotions out of exchanging information.
I don't know what most men would be happy about. And it really doesn't matter. What matters is finding a way to talk with your husband so that both of you are happy.
You ask why the detail of a buckle is important to your husband. I ask why is it important to you? Could you just accept the boots because he had the thought to buy them for you? I've received gifts which were unsatisfactory to me at first only to love them later once I accepted them as a gift of love. At first, I was thinking of what I wanted instead of focusing on how they were showing me that they loved me by giving me the gift.
Because you were there and he asked you, you were right to voice your preference. I suggest that because of your attitude he responded with attitude or perhaps his attitude spawned your attitude. For good communication to occur we have to suspend our attitudes and talk in a loving way. That is where Non-violent Communication helps.
