I have worn the Castelli Evoluzione shorts for several years, and was dismayed to see that they changed the way the pad is attached. The new style stitching is a chaffing problem. The Velocissima is the only style I've been able to find that has the original, zigzag stitching on the pad, so I ordered them. Sometimes Castelli runs small, so I ordered a small and a medium. I wear a small in all other brands of cycling shorts. Well the small was so small, I couldn't even get them on. The medium was snug, as they should be, but the leg bands were huge! They flared way out from my leg. They would have to be taken in at least an inch or more to fit. I don't know anyone that could fix/alter these, so I had to return. Totally bummed, because I haven't been able to find any cycling shorts that I like as well as the old Evoluzione's with the zigzagged stitched Kiss Air pad.
