they should both settle for the $39 ones since they would pay less ;) but I guess you mean they want to pay an equal amount, so
($56 + $45) / 2 each or $50.50 each
alternatively, they could pay proportionally to the number of shoes they get:
"A" pays 2 * ($56 + $45) / 3 since he gets 2 shoes, and
"B" pays ($56 + $45) / 3 since he only gets 1 shoe

There is a wonderful moral question here as well as the obvious math problem. The math problem would be to calculate the total list price of the shoes that each friend will obtain. Call these numbers A and B. Then calculate the total list price of acquiring all three pairs of shoes. Call this number T. Then calculate the actual money required to be paid to purchase the three pairs of shoes. Call this number P.
friend A should pay A*P/T=69
Friend B should pay B*P/T=32
The moral question of friendship.
If A is really wealthy then he might thank his friend for saving him some money and give him half the $39. Instead of saving 13 dollars B would then save $19.50.
On the other hand if B is the wealthy one he might say that he was going to buy the shoes anyway. He might just offer his friend to take the third pair for free and thus save his friend 39 dollars rather than 26.
What do you think.

They must pay a total of $56 + $45 = $101.
If A had bought the $56 and the $39 alone, A would have paid $95, and B would have paid $45
Prorating the $101 using these values,
A = 95*101/140 = $68.54.
B = $101 - A = $32.46
A straight 2:1 proration would yield
A = $67.33
B = $33.67,
But, since A received the greater value the 2:1 is not fair.

Total cost is $101.
Before the discount, the cost was 140, for which A would have been responsible for A 67.9% of the cost. Apply that proportion to the sale cost.
A - 68.54
B - 32.46
Not wanting to look like a penny-pinching jerk, A says "Just give an even $32." B says, "Right on, man!"

So between the two, they are "saving" 39 dollars. Since Friend A wants the $39 shoes, she should give half of the $39 to her friend.
