These slippers do fit very well and, unlike other reviewers, I don't find the heel to be overly voluminous.  The new elasticized fabric is a step up in comfort from the old canvas slippers - the only option if one did not take enough classes to properly stretch out a pair of leather slippers.  But I must say I am not a fan of the split sole construction.  Perhaps it is an inherant evil that the lighter fabric cannot support the thickness of inner sole material that more traditional materials can?  I don't know...but one feels the pleated fabric of the toe like a flat pebble beneath the ball of the foot.  For simple stationary stretching and my Ballet Beautiful workouts, this won't present an insurmountable obstacle, but I can't imagine that any time at all spent on demi-point would not be very uncomfortable indeed.
