I got mine at bps where I could try them one. Found nothing anywhere close locally that fit. Still had to get a shoe size larger to fit the rest of me. Think about what kind of surfaces you'll be standing and walking on before you buy. Since I use mine more in small streams, got the felt soles so they will slip less on the rocks. A buddy has rubber soles and has a real problem keeping balance on slick spots and wears himself out catching himself all the time.
