I have narrow feet - AAA heel and AA ball and we were able to heat mold my edea concertos.
I just switched from Harlick 2 weeks ago and let me tell you, these skates are magical. I am an adult skater (34) who skated as a child and had 2 triple jumps, now I am getting all of my doubles back and on the 2nd day that I was in my edeas my double loops felt flawless. You need to find someone that is used to fitting edea skates in order to get them molded like that - the coach who did mine put them in a box with a hole cut out and put a hair dryer in there. They sat enclosed for about 10 minutes. After that she took them out and squeezed the heel area together. I then put the skates on and tightened them as hard as possible.. then walked around a bit and let them cool down. They've been perfect since I got them.
The material they use is not leather which is why it heat molds so easily - carbon fiber practically melts in your hand when heat is applied so when those hot boots were taken out of the box they took the shape of whatever we wanted to do to them. The inside is a memory foam like tempurpedic - all it needs is your body heat and it forms to your feet.
I feel like I'm skating on air. I've been a harlick skater all my life and I still hold a special place in my heart for them, but these skates are something else.
