Placing a shoehorn on each bench in the locker room anticipates a need and giving one to each guest is a nice souvenir reminder of a good time. The pro shop can also include one when a member or guest buys a pair of shoes. At The Greenbrier my coworkers and I put one in each pair of street and golf shoes when guests checked out from the locker room.
Shoehorns are available in plastic, wood, metal or a combination of each. Based on practical work experience I say that Crystal Tex makes the best 7” plastic shoehorn. If you prefer all wood then I suggest the ones from B & W Import and Export, which was in the guest room closet at the Four Seasons Chicago.
The shoehorns that impress me the most are the ones made by Long Handle Shoe Horn which I first saw at Conway Farms Golf Club (IL). My one main concern about them is that they might “disappear” if you know what I mean. However, they would make for a nice gift by being avaiable for purchase in the pro shop. The locker staff can keep a few on hand for personal service as well.
