Having just looked at another shoe thread it seems lots of you find Birkenstocks comfortable.
Last Summer I bought these and I find them so uncomfortable. The soles are too hard and the raised parts dig in. They are now resigned to pottering around the garden in as I can't wear them for long without them hurting.
I didn't realise they made them in quite a few different styles until I saw them here. Which style is the best for walking around for a few hours in?
