This looks great, and I look forward to reading your article about it!
As for things to improve,I'd remove the '!' in 'View Details!' because an exclamation mark conveys excitement of some sort and there's only so many times I can feel excited(!) about viewing details of ballet shoes.
Also, this could come in a later iteration but instead of having a modal that says 'View Details' when I hover over a pair of shoes, it could say 'Quick View' (or something of the sort) such that clicking it would open a pop-up/lightbox-type thing that shows me a summary of details about the pair and allows me to quickly add to cart. (I have no data to say if this is what your customers will definitely like, but it might be worth a try.)
I'm not sure you have any control over this bit, but including more pictures of a product (preferably pictures that show different angles of the product) is always nice.
Finally, I'd fix the alignment (and maybe positioning) of the elements highlighted in blue.
I hope this helps.
