With plus sizes, the trick for any shoe is in the comfort. Not every shoe that fits you will serve your toes well, so you might want to use some tips:

Choose shoes that have enough breathing space for your toes if you are wearing closed shoes. This ensures comfort in your toes in turn keeping your body relaxed.
Choose the right size of heel; heels are gorgeous but they can really harass you if you pick the wrong type. A high heel shoe with a platform is quite comfortable and easy to move about in for some plus size ladies while lower heels work best for most. Very flat shoes sometimes don't feel comfortable if you are walking or standing for long therefore a wedge heel would be best to reduce back strain.
Very heavy shoe soles might get you easily tired or slow down your walking especially if you are a busy woman. Anything that feels like some piece of rock has been tied to the bottom of your feet is a big no except if you are willing to pay the price.
Go for gorgeous!- Any lady just wants something attractive and if we share the same views, an attractive pair gets you more psyched up to walk. Pick your favorite colors and brand and the motivation will be automatic.
For strapped shoes avoid very tight straps. Choose slightly loose straps for sandals to avoid marks on your feet after a long day. Elastic straps are the best because they adjust according to the size of your leg.
Look for absorbancy qualities in the shoe if it is closed; you do not want sweaty smelling feet.
