Prior to purchasing any shoes, get them both on your feet and walk around. During this walk, ensure the shoe is comfortable and that it doesn't slip and slide as you walk. Try on a few different sizes so you can figure out which one fits the best.
Look in the clearance racks. New shoes come out all the time and shoes are being put on sale on a regular basis. Before making a shoe purchase, look in the sale section to find out if there are any shoes in the style and size you want to purchase.

Beware of forcing your shoes or sneakers to multitask. Not every pair of shoes is great for every circumstance. Did you know for instance that there are differences between walking shoes and running shoes? You'll be better off by identifying your need and then choosing a shoe that fits it well.
