Canon SHOE COVER ER-SC3

It fits perfectly on my R6 II and clicks into place with a reassuring solidness that makes me trust it'll stay put. The slight rubbery texture feels like it will actually grip and protect the shoe from dust and moisture.

Slapped it on my R5 and it clicks into place with a reassuringly solid feel—no wobble at all. The rubber seal around the edges gives me peace of mind when shooting in light drizzle.

Finally, a cover that actually stays put on the shoe without popping off in my bag. It's thin and light enough that I forget it's there, but the snug fit gives me real peace of mind against dust and moisture.
