Are the Puma GS-Fast shoes waterproof?

Yes. The upper is built to keep water out in dew and light rain. Standing water or heavy downpours can still soak through over time.

Are they spiked or spikeless?

They are spikeless, with a molded rubber outsole. That makes them comfortable to walk in and fine to wear off the course, but they grip less than spiked shoes on wet or steep ground.

They run true to size for most men, in a medium width. Golfers with wide feet often size up or look for a wide-fit model.

Can I wear them off the course?

Yes. The low, sneaker-style profile works for casual wear. The soft rubber outsole wears faster on pavement than on turf.

How do they compare with spiked golf shoes?

They are lighter and more comfortable to walk in, but give up traction and lateral stability. Choose them for dry conditions and walking rounds; choose spikes for wet weather and steep courses.
