The Nemo footpockets will work well in combination with a softer blade bumping it up in stiffness half a level or so because the bottom of the footpocket is nice and stiff and doesn't allow the back of the blade to poke through it. The tendons are slightly stiffer than omer or H Dessault. The actual footpocket isn't too hard and I find it comfortable. I'm foot size 11.25 and the 44-45 size fits me well allowing me to dive with Lycra socks.
