I'm looking for advice from the Styleforum Hivemind: After my Rowenta crapped out (broken steam trigger), I went for the Reliable IronMaven J420. So far it's great, lots of steam, comfortable handle (though I'm getting used to the top button for steam rather than the trigger). I'm wondering about the teflon ironing shoe. I know these are recommended to avoid shine, but do you find yourself using them all the time or just on delicates? I tried it out, and it seems to knock down the heat considerably, I'd guess kind of like a pressing pad. So, what's the verdict? Teflon shoe for everything, or just for dark and delicate items?
