It's fine, though it does become more difficult as your pregnancy progresses. In general, walking is good for you during pregnancy; it reduces your chance of blood clots and keeps you in shape.
One thing that can help when you're standing for long periods is support hose. These provide compression so your legs feel better — and they help hold the blood in so it doesn't pool around your feet and make them puffy and swollen. Wearing a maternity belt can also help at the end of the second trimester and during the third; it supports the abdomen and helps redistribute some of the weight.
