Great shoes, ran a tad too large. Use: I use my microphone for my WFH office to record lectures and just as a better mic for zoom meetings. Seems like a decent replacement except the wires are perhaps not as pliable as the original product. Fits as expected, very comfortable. Also get sore balls of my feet and these boots have proved to be very comfortable. 5mm adapter for an additional $9. 15 mins to install fake news ,agreed with the others no stickers no arrow inducating right, left front or rear ,allen bolt does not go all the way down to catch with the car studs ,instuctions not easy to follow ,trim which rubber should not have to cut drill anything . I installed this on a Realistic LAB-2200 linear tracking table. Je lai fait tomber. The next 2 wear defective.
