Hi! You have a great collection! I love pink too! I used to wear my yellow ones often (I got the matching bag), but recently, I am drawn to white, pink, and orange! I have a bright orange pair that is super fun in the summer. By the way, I have red ones too! We are shoe twins!
On black...
All I can say about black is everytime I buy something Chanel black, I think "oh, it's a classic, I must buy it." Then, after the inital excitement of the purchase and wearing it maybe 4-5 times, I am tired of it... boring! It's just a boring black ballet. This is also true of my black Chanel bags which I never wear. So... think about what outfits you will wear with black ballets.
For me, I love color! And...if I am wearing an all black outfit, I love wearing all black with my beige ballets! That beige with black cap toe is such a gorgeous combo!
On the sole, I keep the sole as-is. Why?
Because to me, a ballet is a feminine shoe, and the sole is meant to be feminine and thin. I have seen people who resole their ballets with a rubber sole, and yes, if you look at it from the top view, you would not notice. However, that is not real life. You, and others, see your shoe at an angle, and you see the sole. Plus, you see that "cut" where they put the half sole on, and I think it takes away from the beauty of the original sole, even if the sole is worn. It is no longer one nice piece of leather; it's all chopped up. I travel a lot, so I am always sitting around at airports, people watching. To me, when I see a ballet with a rubber sole, it ruins the look for me. That's just my opinion of course.
Everyone is so afraid of wearing out the sole, but for me...
I have walked miles and miles in my ballets, including harsh walking like the concrete streets of NYC. For me, the leather gets all beat up before the sole. My soles have never had a hole. I buy new ballets because the leather is beat up, or I've worn them so much they are out of shape. I never had to replace a ballet because the sole had a hole.
One thing I do however, is watch the heel and get new heels. I see a lot of shoes with heels that are worn out which is not an attractive look. I regularly check my heels to see if the are getting worn down.
Oh, one more thought... the original heel on the ballet I find a bit slippery as that rubber portion is a stiff rubber. Either that, or I walk funny and my weight is on the heel. If you also find the original heel a bit slippery, just replace it with a new heel. My cobbler has heels that are made in Italy, and the rubber portion is a bit softer. Hence, it doesn't slip as much to me. It's not a big deal, but just FYI in case you notice that.
By the way, do you like royal blue? It's rare color, and it's back now after several years. I have this color and love it. Just FYI...
