next time I’m at my hangar I’ll snap some pics of my ACA boots. I’m not sure if they’ve changed them (ordered them maybe 6 years ago) but the material wasn’t much different from the Airtex material.
According to Chad at ACA, that was quite a while ago. They now put carbon fiber floorboards in their new airplanes but before that, they used Flightline Interiors after AirTex for years prior to switching.
Interesting side note. I bought some Lift Aviation shoes so I could get my size 14’s on the rudder pedals from the backseat with a broad of backside front seater. The plastic heel sliders have created dents in the carbon fiber floorboard installed in the newer ACA planes.
