Yes, I wear mtb shoes and use SPD pedals/cleats. On my gravel ride last weekend, we came up on a bridge under construction. The gravel on either side was unrideable, deep and loose, so we walked. The workers were nice enough to let us cross the bridge even tho they had just laid a section of fresh concrete, we just had to carry our bikes and walk along the edge on a section that was prob less than a foot wide. Then we walked through the loose gravel uphill on the other side until we got to where we could ride again. I def would not want to do that on road shoes with SPD-SL cleats.
I wear Fizik X5 Terras, they work very well in a hike-a-bike scenario.
