I am surprised that any therapist these days would recommend the 4 footed cane. Those are frowned upon by almost any therapist I know. Here are the reasons they tell me;
1) Most 4 footed canes are solid construction..which means all 4 feet must be touching th eground at the same time.
2) Often, in order to get all 4 feet to touch before stepping..one has to place the cane just right..perhaps uncomfortably far from him.
3) Solid, one piece construction is bad on any irregular surface...the canes with 3 pads are better..especially if they have a swivel near the ground.
4) I have built some small forges to be used for outdoor demonstrations, as well as a couple podiums for outdoor..usually graveside services. Three legs beat four every time..you can almost always get three legs to touch ground, while rarely can you get four legs to stand firmly.
Hint for an all wood cane that works well...whether you find it natural, steam bend it or cut it from plywood..
Bend the top 4-5 inches, so it fits the hand like the grip on your favorite pistol. A pistol grip shaped top is so much more comfortable than a perfectly straight one. It is t e natural angle for your wrist to be comfortable..
