I wear latex gloves for work and never put my nails through, maybe you have the wrong size gloves. Also what cornflour? unpowdered is the way to go.
Sorry to get "serious"
Latex allergy is a real issue and many of the powders act as irritants and sensitisers exacerbating the issues
If you go down this route - unpowered nitrile gloves

Out in the sticks dock leaves make good protection if you have to handle the chain.
