I suppose I'm more of a traditionalist and I was never particularly fond of that style of sock. However, that being said - wear whatever "floats your boat" just consider to be respectful of the kilt and the tradition.

Would a gray pair with the stripe provide a little less contrast and not take the eye away from the kilt? It also might not look half bad when worn with a kilt pleated to stripe. Or as others have suggested worn with a solid color kilt.

Cheers! Bill
