Thanks for the feedback and advice.
I probably should explain - l submitted a post a while back, asking how to safely pose in the shoes. The response was about 50/50, some said to not even put the shoes on, while others suggested exercises and ways to prepare for the shoot. As l had over a month to prepare, l saw a dance teacher, did lots of strenghthening excercises and practice at home, and saught advice from other dancers to prepare. l knew it was risky, and had no desire to damage my feet / ankles. l was going to prepare as best l could, and do what felt comfortable on the day. l wasn't out to fool anyone into thinking that l'm a professional.
l had already pre-warned the photographer that l may not be able to go en pointe at all, he was easygoing & there was no pressure on me in that respect. It wasn't meant to be a "ballet" shoot per say - the shoes just happened to be part of the wardrobe.
We put together a range of poses that did not all require me to be en pointe, but could still show off the shoes ie. the shot where l'm kneeling. There were also good "props" for support - l had a beam over my head within arms reach that l could hold onto to get my balance, as well as a large crate to lean on, a chair and a walking stick that l used to support my weight when required, all craftily photoshopped out! In a nutshell, l didn't jump into the shoot blindly, there was a lot of thought, research and preparation that went into it.
