FYI: the Overijse place is accessible by de lijn buses from metro. It's in the centre of overijse. Easily walkable from the buses

They do informally: they asked me to run in a number of different types of shoes to analyse your gait/ pronation etc the first time I went. I have always found them very helpful and have got 2 great pairs of running shoes there.
