Hi yarnsforth, thanks for posting.
I wonder if the colors in the photo are throwing things off here. If not then I'd have to suggest that the color of the shoes is a bit 'challenging' in terms of working with the gray trousers. The trousers seem so dark, the shoes so light. I get you were trying to blend them together with the socks, but there's not enough pattern/color blending in the socks to somehow bring it all together for me.
Perhaps others will call me out as mistaken here. I hope this is helpful.
