What are the most comfortable shoes for pregnant women? Where in Manila are they available? Thanks!

I've bought a couple of shoes when I was pregnant with my twins. I want something that will be really comfortable. With the weight of my tummy and swollen feet. I tried looking for shoes that I'll can use everyday. I've bought a regular flat shoes. But unfortunately I've felt that its not giving the extra support that I need. So I tried looking for shoe stores that has thick insole cushion. And I was glad to find the right pair in Payless. Particular brand I had purchased is Dexflex. They have sandals, flat shoes and casual shoes. And what I really loved about it is the cushion and very stylish designs that can go with any of your outfit. Payless has several stores in Metro Manila. Located at Robinson's Mall and Ali Mall. Hope this helps.
