Perhaps their popularity dropped when security regulations were introduced limiting the size of your cabin baggage to 56cm x 45cm x 25cm, together with (until January of this year) a strict 'one bag only' policy?
There are no dimensions quoted here (so I can't be sure that it would fit into your bag) but this might help: http://www.ebuyer.com/product/124794
You can still buy portable steppers. They are inflatable and have 2 sections with a join in the centre, one side for each foot and can 'step' on it like I think you are describing?
Marks & Spencer sell them (they have a small travel accessories range) usually near ladies toiletries/gifts.
Boots also seel something similar which they also suggest can be used as a back pillow/support.
