Some friends of mine who lived in germany for a while tell me the the local ID an american tourist by tennis shoes or sneakers. Those are "gym" shoes to them and only worn in the gym.
And by technical people in general :-) You will not attract any negative attention with that, no worries.
I'll probably still wear mine for the day stuff though.
Please wear the type of clothing you feel comfortable with. We are going to stick together for three days and it is supposed to be interesting, informative, productive, and last but not least, lots of fun.
