Unfortunately, the leg / ankle position "geometry" on elliptical machines isn't the same for all machines. Some have more feet / ankle motions and some force more up/down leg motion. Each Elliptical machine is designed slightly differently. During the years, I found that some human body's can handle their Elliptical machine and others' cannot. It depends on one's unique body and the unique geometry of their specific Elliptical machine.
The "tingling" in certain body parts is sometimes from a minor pinched nerve. Or, putting the feet / ankle into a body position it doesn't like anymore (especially over a long period of time). The "tingling" or pain feeling is an early warning of the human body stating, "hey man, I don't like doing this anymore". Ya. Sounds corny but its true. The body is telling you to do less time / less distance - on this unique body position.
As a suggestion, do less and less Elliptical machine time. Try 1 time every other day. Or, 1 time every 3 days. For the other days, may I suggest an exercise that uses different body positions. Like walking, swimming or some other task that works different parts of the body.
As my doctor often says, "if it hurts, don't do it". Same holds true for "tingling" feelings in specific body parts as well...
Hope this helps...
