I recently rented plastic mountaineering boots from REI. They were correctly sized. These caused a great deal of pain (to the point of almost being disabling) on the lower side of both outer ankles after the first day's use. The area was bruised and blistered. Yes, you could say I have bony ankles.
In my seriously dated mountaineering experience I used Sorrels and flexible crampons without any foot or performance issues. These are obviously limited to moderate slopes but at my age I'm not going to start climbing any ice walls anyway.
Is there a trick to avoid the above symptoms with plastic boots? I thought about moleskin but didn't have the opportunity to try it before the damage was done.
Is there any issue with using Sorrels and flexible crampons for moderate slope routes (beyond not being one of the cool kids)?
Thanks in advance for any advice.
