I tried on the Katahdins at LL Bean and found they ran TTS, an 11D for me. My Wolverine 1K Mile boots required a half size down to 10.5. The SA where I bought the Wolverines indicated that they can order half sizes in the original 1000 Mile boot. thanks but i'm really wondering more about the width. If I need a wide in the katahdins will the 1k fit. how is their width compared to the bean. if the regulars in both are the same it prob won't work, but if the 1k mile is wider in general than maybe.
