>>1557818pinned flats won't necessarily ruin regular shoes. they're pretty good for foot retention.
the worst thing for ruining regular shoes are classic style cage/quill/track pedals imo with those thin ridges that cut into your feet
i've never really tried them but i think those fixiefag straps seem kinda retarded. and if you have shit pedals already don't just add straps to them.
maybe try pic related mks gr-9s with straps and cages. those don't have thin ridges to cut into your shoes. Seem pretty good. Maybe not though if you have big feet. They're kinda smol apparently
