Lizars, were the heels a lot thicker? I think that would be OK on heels, I'm not sure about toes. Hmmmm.... I've only made a few pairs of socks, only 2 w/sock yarn. My pink sox are so warm I don't wear them much. The others aren't as warm but they're still warm enough I can only wear them when it's pretty chilly. I think both were made with LB SockEase. I'm thinking of cotton sock yarn so I can wear handmade socks all year. That would be luxury!
