I have both. For longer rides, I use my Sidi's with socks. For shorter rides and tri's I have Lake tri shoes, they were about $50 from Nashbar I think. I really like the ventilation with the tri shoes, and without socks my feet are definitely cooler, especially out of the water. The one velcro strap gives a little less snugness and more room to breathe. I say give them a try(sorry for the pun).
