Bad at buying

Why on earth am I so bad at buying clothes and shoes??? It takes me hours longer to decide than most people… and then the decision I make is almost always a poor one. Example… I need some good lined winter boots to take to Canada. Having never bought winter boots before, I actually decided to buy two different styles to wear a little around the house to see which was the more comfortable. As it turns out, the answer is neither. One is too short and the other too tight. Why did I not notice this in the store???

Any handy hints on how to make better decisions when buying things that actually need to fit and be comfortable would be greatly appreciated…
