Brand new, unused Grishko ProFlex 6XX! The shank is H! I'm selling them because I no longer have the opportunity to wear them! Thank you! :) [Product Description] These are the popular Grishko 2007 ProFlex pointe shoes with a harder shank, Flex Shank Hard. This is the optimal pointe shoe for those who like the softness of the Grishko "2007 ProFlex" shank but find it doesn't last long, or for those who find the regular 2007 too hard. While regular ProFlex uses a shank with a hardness between S and M, this is Flex Shank Hard, making it harder than regular ProFlex. However, unlike a regular hard shank, it maintains the flexibility and lightness of the Flex Shank while being a hard specification, giving it flexible hardness. And since these are PRO model shoes, they retain the sound-dampening feature of the 2007 ProFlex.
