One more note on shoes and feet...
If you aren't putting weight into the foot then the toes should be pointed ..even when you are standing and especially when you are doing floor moves . Even in boots. The act of pointing will engage the muscles in your leg and instantly give you better lines...so please point.
If your foot starts to cramp..and it will, just realize the more you point the more that little foot muscle gets used to it.
Try flexing and pointing 50 times on each foot.
Then your shoes might start to stretch out. Just by those Payless SS pads I talked about.
