Very likely. I've had more episodes of tingling and numbness the past few months, and it coincided with a deliberate change in my pedaling style. I switched from higher cadence, around 90-100 rpm, to around 75 rpm and harder gears, after noticing a pattern of my heart rate pegging way too quickly when spinning, especially on climbs. I suspected too much energy was wasted on simply lifting my legs for the next downstroke. I was just trading one problem for another with no real net gain in performance.

A slower cadence and bigger gears lowered my heart rate at the same speed/perceived effort, especially on climbs. But the additional pressure on the metatarsals occasionally causes circulatory problems. So, as you described, I'll occasionally switch back to spinning in easier gears, stand to pedal, etc., to restore blood flow. And good insoles help (the ProFoot Miracle insoles).
