I have found that @ night I'll put some weight on my toes ie. a pillow/ heavy blankets and use the weight to strech my feet in the pointe position for a while while i'm in bed before I turn in for the night. This has helped me in walking in my ballet boots. Also I use Leos' gel pads ( Pink ones) for toe padding also I put some thin eva rubber padding on top of my feet to pad the tops of my toes as well. I bought the gel pads @ our local dance store. When I started out I used the hallways in my house as they helped me when I needed to balance my self. Once you solve the toe padding issue then it's a matter of training your ankles/legs to take the strain and build strength in your legs to be able to walk in bboots. I have had my boots since Nov. last year and I try to walk in them 2 to 3 times a week for @ least 1 hr. @ a time. I have gotten to the point now where I walk quite well( not as well as Pata) but my legs get quite tired after my sessions after all I'm 62 years old but I hope this will improve. The more you can practice/walk in the boots the better you'll get. I'm glad to see more people giving these things a try.
P.S. I also fashioned a gusset( check my other posts for details) between the heel and sole of my boots to make the heels stronger. I have have read stories of people braking the heels off there boots and I didn't want this to happen to me especialy while I was walking in them.
The Best to you.
