Scarlett P. ★★★★★

I was surprised how easily the PSA abrasives stuck to this shoe — no slipping at all during use. The rigid construction made long, straight passes feel precise and controlled.

Nicholas I. ★★★★★

Finally got this file shoe to replace a worn-out one on my DA sander, and the rigid backing really keeps the paper flat during long sessions. Swapped it in under a minute since it's just a straight swap with the PSA backing.

Carter H. ★★★★★

I've been using this rigid air file shoe for a few weeks now, and the 16 1/2" length really helps me keep long, flat surfaces perfectly even. No handle was fine since I attached it to my existing setup easily.
