I have had my Them 909s for a few months already when I started noticing pain on the side of my ankle when skating for about half an hour.
As there are so many people recommending Intuition, praising their liners for their good fit, I got their Premium model, hoping to eradicate that pain.
When I tried them I was promptly disappointed: It hurt even more. I removed that velcro wrap which made it better, but still not better than with the old liners.
I went online and learnt that you could heat mold them, which I tried, not going overboard with the temperature, though. It made it better, I guess?
But it still hurts, so I continued my research and found several people claiming that the liners need to be broken in for about ten to twenty hours. I hope they are right, I will not give up yet.
Update (3 days later)
Two days ago I skated them for three hours straight. At first it felt quite alright, especially my right foot felt fine, but there was some discomfort on my left one.
After a while that discomfort turned into pain, and after another while I somewhat got used to it. I got the feeling that I was breaking in my feet instead of the liners.
Unfortunately, my left foot still hurts when I put pressure on that one hot spot. I won’t skate until that spot has fully recovered, otherwise I couldn’t judge if liner becomes better anyway.
That’s awesome. Glad they’re starting to feel better! It sucks having to power through that break-in period, but I always try to stress that it requires a little time.
The 2nd Skin liners were immediately a fit for me. I have pretty flat feet that are a little wider than usual, and they required almost no break-in time. I didn’t have to heat mold them or anything (you can though if needed).
