Why does Zaroff suggest Rainsford wear moccasins?

In the story "The most dangerous game" by Richard Connell, Rainsford the main character stops at an island while sailing to meet a man we know as General Zaroff. The two men are both big game hunters but Zaroff explains how he hunts what he considers the most dangerous game. Confused Rainsford asks what that is, and Zaroff explains that he hunts humans on his island. After an invitation to join him in hunting humans, Rainsford declines and is subjected to being hunted by Zaroff.
Zaroff gives Rainsford a few items to make it a fair hunt, including food, a good knife, hunting clothes, and moccasins. The reason for the moccasins being that they leave much less of a trail then any kind of boots or sneakers, when Rainsford will be hiding in the woods. Zaroff being the competitive hunter he is, wants Rainsford to have no excuses if he gets found. Hence the moccasins that will make him harder to find in the forest of Zaroff's island.

After first meeting General Zaroff, in Richard Connell's short story "The Most Dangerous Game," Rainsford believes Zaroff to be quite civilized and cosmopolitan. Later, however, he learns the truth: the general is really a sociopathic murderer who hunts men. Zaroff, on the other hand, seems to believe that what he is doing is sport. He boasts about how he takes care of his future prey—sailors from ships that have wrecked on the rocks around the island—in his cellar "training school." He tells Rainsford,

"I treat these visitors with every consideration. They get plenty of good food and exercise. They get into splendid physical condition. You shall see for yourself tomorrow."

When Rainsford rejects Zaroff's invitation to hunt one of these sailors, Zaroff decides to hunt Rainsford. The general even seems giddy to have a chance at matching wits with another big game hunter such as Rainsford:

"Your brain against mine. Your woodcraft against mine. Your strength and stamina against mine. Outdoor chess! And the stake is not without value, eh?"

To show how sporting he truly is, Zaroff provides Rainsford with food, a good knife, hunting clothes, and moccasins, because, Zaroff asserts, "they leave a poorer trail." Indeed, the moccasins do help Rainsford, who eventually outwits the general and kills him in his bedroom.
