Not sure about aero effects, but this socks are comfortable

Good socks, just small according to size

Good socks, just small according to size

Comfortable and look good, got a second pair in different color. Sizing as described. Haven't had these long enough to judge durability.

Liked the fit and support of this style but found the fabric snags/pills rather easily. Would not purchase this style again.

Very thin & lightweight, Good for summer & allow plenty of room in your shoes. A little too much compression but bearable (not like really tight Pearl Izumi socks).
