SeaniBu - Normally, I prefer the all white boots look as well. (I DO NOT like the nude boots AT ALL) But, in some cases the tights over the boot looks better. Oddly enough, this preference is random. I might like the white boots on a skater wearing dress 1 but with dress 2, I hate it. So, theres not rhyme or rule with me.
I DO NOT like it when skaters have their tights cover only the top part of the boot - just the laces - at least in comp.. It looks slouchy to me and very casual. I noticed that Rachel Flatt does this and I really dislike it. I also don't like it when for comp.'s they pull the tights down over the top of the skate and hook them under the heel. There is something not right about it. Bebe was like that this year with her pants look. I generally don't like pants for comp. Practice is fine.
However, I can appreciate the funny look of elephant feet when the boots are covered. I think it really depends on the skater, the length of the leg, the actual size and curvature of the leg, the dress and how chunky the boots are. Some boots are just chunkier than others...Klingbiels are that way - at least some of them are.
