Richard bought me some walking shoes today ready for our walk up to Machu Picchu. I said all shoes are for walking in. (An Idiot Abroad: The Travel Diaries of Karl Pilkington – Karl Pilkinton) I know very well that you can end sentences with a preposition, but here it seems awkward and redundant to me, similar to "Where are you at?". Does anyone agree or is this sentence perfectly fine? Thank you in advance.
