It could be worse, you could take a half size in shoes, and end up being eternally condemned to shoes that are either too small or too big.
Regarding flaws and dysphoria, we are acutely aware of our flaws and therefore assume everyone else is. In fact the opposite is usually true. Your perception of your flaw is magnifying it in your mind, I had a similar thing with my shoulders when I started out, wearing them un covered made them feel huge, despite my hips and shoulders being in line with each other and I would be fine if the were covered.
Things you can do - rocking styles that don't draw your eye to your feet will help you deal, leggings and ballet pumps may be a cute look, but if it's making you hyper aware of your feet, try adding leg Warmers or wearing boot cut jeans. Being born cis doesn't mean you have a perfect body, stuff like foot and hand size is genetic rather than from the effect of hormones.
