Lot of the same advice given. I got one to watch out for. There is the problem of a cage being bent so you only get your toe in but there is also the situation where, if you are wearing lace up shoes, the laces get caught on the strap loop of the cage when trying to slide your shoe in the cage. Trying to pedal with your big toe over the pedal axle is not very effective!

Like so many things, with a lot of practice, it really isn't a challenge but rather part of the joy of being competent at doing something other this is too hard or useless with current designs. Part of the C&V thing, it is more than just the bike.
