@LauraS Thank you for reaching out! I'm sorry that you're experiencing pain with a pair of boots that you have gotten so much use out of! Without being able to see the boots or look at your foot and ankle it will be pretty hard to diagnose what the issue might be. I would recommend scheduling an appointment with an outfitter at your local REI who is a footwear expert. Given all the variability to fitting footwear it could range from the padding has compacted on the ankle part of your boot to needing an after market footbed to stabilize your foot in the boot. The expert at the store can take you through all the options and see if we can get you back out on the trail in comfort. I hope this helps and best of luck on your adventures!
