Just opened my first custom fit order (Melanie) & my heart dropped as there was no side zip. "I'll never get these on" I wailed (high instep). WRONG!!! Holding the side tabs & pulling they slipped straight on...yay!!! I am absolutely in love & went straight online & ordered my second pair (Tillie) in the same custom fit..please, please, please do Ariel in custom fit - they are gorgeous but I need a 48 cm!! Btw I'm (I'm a young) 59, wish you'd been around years ago! X
