How much did your shoe size change?

I went from a 10.5 US, 43 Euro, to a size 11 in the first month....About 2 weeks ago I was at size 11.5 US and 46 Euro....today I went to buy shoes with my Correct Toes putting my toes in the right place, and only a Size 12 would fit properly....thats 1.5 sizes up!

Its crazy to think that I wear a size 12 now after over 25 years at size 10.5.
