As you start carrying more weight your feet need a little more support and it gets harder to bend over and put on shoes. Slip-ons are the easiest but when you need a sneaker I always prefer something I don't have to tie. This pair from Cole Han I can slip on and off without tying. I also wore this velcro pair of Vejas my whole last pregnancy and loved how easy they were to get on and off (and they go with everything).
