Got it. Do you think there is actually a chance I could wear these in a size 9 and the heel slip would go away? It's just so confusing to me that they would conform around my foot. It seems if they are too big, if anything they will stretch. Edit: I guess heel slip would come mostly from length...but what actually feels big on me seems to be coming from width. I can't imagine these would conform to me though. no, what i was saying is they wont stretch much in the length (in reference to your mg's), at least that is what i have found. in the width, yes, they do mold to your foot over time. yeah, the problem i had with my 8E anglers was the leather around the toe area started to pinch, its really hard to explain without seeing it. and i dont know what this is called in shoe terminology. but mine were leather, not suede. so you might not have the same issue. as long as you have some room between the end of your toe and the start of the shoe and they dont slip, you found your size. they should be tight, but not like you want to chop your toes off tight.
