Just an FYI type message. I just wanted you guys to know that I've found the perfect shoes for SP umpires or working the bases for FP. You may have seen a lot of players wear them. They're comfortable, durable and they breath very well. They're made by Boombah. There are a couple of different styles that you can get in all black. I wore a pair all of last season and they're still in very good shape. I bought another pair for nats and those will be used as my local tournament shoes while my last season pair will be used for league games. Oh BTW, they clean up very easily with a damp rag. Here's a link to the pair I wore for nats...
