Walk, walk, walk...
You never can stretch the toe-box of a So Kate with a stretcher, you have to brake them in by walking and walking and walking.
Every shoe, especially a high heels and even more especially a really high Louboutin pump has to be broken in by our own toes, by walking and walking and walking, the more tears the better the are walked in!
I actually own more than 55 pair of heels, most of them single soles, higher than 120mm. And I have broken all of them.
Same heels are easy to break in, sandals of corse but I have also goot experience with GML pumps and YSL Tritoo.
Same heels are harder to break in, Casadei Blade pumps and boots e.g.
And same are really hard to break in, in my opinion unfortunatelly Louboutins belong to these sort of heels.
When I buy a pair of high heels, I normally take one size smaller, because the smaller the nicer. In case of a Louboutin heel, I take the correct size and normally try them in the afternoon when my feet are a little bigger than in the morning, since I normally wear my Louboutins at night when going out, while I wear the Casadei and other heels during the day, at work or the lower ones (100mm) at home.
When I`m back home from shopping I put them on and walk arond at home for hours, mostly on a soft carpet, till I cannot longer stand the pain. In the maintime I heat them with my hair dryer to get them more soft and elastic. At the end of the walking I care for my feet. For sleeping I put on the shoes again (my husband is quite happy with that!!) and take them for the whole night. The next 2 or 3 days I do the same procedure, on the forth day I walk around my house for an hour or so, its very differnet walking on pavement then at home on the carpet. I normally do that for another 2-3 days, after then I can say, these shoes are pretty walked in and I can dare to go out for a party or wear them on a shopping tour. So for all my Louboutin pumps it takes me more or less a week to brake them in.
But the most difficult shoes to brake in are the so beautiful Louboutin Mandoline booties, the are one of the sexiest and most beautiful heels ever, but they are in my opinion by fare the most hardest heel to walk with, it took me several weeks of training with lots of tears till I was able to wear them for a wholke day and walk in them in an elegant, sexy way.
