I have just started ice skating as an adult skater. My first pair of figure skates were given to me as a present, and had no ankle support. I have been given a secondhand pair which are a lot more rigid and allow me to skate with my knees bent a lot easier. They are comfortable when my knees are bent. However, when I straighten my leg, the skates really cut into the back of my heel/ankle and it’s quite painful. The length and width of the skate feels correct. Is this common with more supportive skates? As I am a beginner - and have not been to a shop to try on different brands yet - I don’t know how they are supposed to feel. I only have rental skates and my previous pair for comparison. I will look into buying my own pair quite soon and be properly fitted, but just interested in getting an opinion on here as well as to why they might feel like this.
