When will baseball players wear stirrups again?

Sock choice in MLB is up to each individual player. They have no regulations on what they have to wear. The NFL, however, requires each team wear a specific type of sock and they do fine individual players who do not follow this dress code. If you log on to espn page 2, Paul Lukas writes a blog every week or so called uni watch. He describes uni changes that take place in all sports and even throwbacks, as well as providing pictures. It's always a good read and he seems like the type of dude that would be able to answer any questions you have regarding uniforms in pro sports. Hope this helps
