Hi,
now I do have mine! The quality is OK - I ordered after measurent of my feet and the shoes do have a snug fit. So I'd agree with the measuremnt instructions which are made on their website.
About the metal heels, the strap is closed with a simple screw.
If someboady need close-up pictures let me know via email - it will take a while until I've them on my website.
best wishes
Joak :)
