SimmsG4 Boa Boot - Men's

Designed for the technical, demanding angler who's looking for the best wading footwear on the market.

Built for the discerning, technical fly-fisher-person who invests in only the very best, the Simms Men's G4 Boa Boot provides sheer performance, comfort, support, and amazing traction while you wade. Its waterproof PU-coated leather and TPU-coated textile uppers supply maximum abrasion-resistance, durability, and protection while the G4's fully lined neoprene fabric adds wading comfort, cushioning, and easy-on and easy-off. A Boa closure system ensures a precision, on-demand fit, a smooth, even closure with no pressure points, and one-handed adjustment. 

Designed with Simms RiverTread platforms, the G4 delivers maximum comfort, performance, and slip-resistance so you can concentrate on making that perfect cast. In addition, the RiverTread is both trail-ready and wading-ready, thanks to its molded 3D footbed with arch support and ball flex that align your foot for all-day comfort and optimal bio-mechanics. The molded dual-density EVA midsole provides cushioning for hiking comfort and enhanced proprioception. Simms also equipped the RiverTread platforms with molded, minimal, and hidden TPU retention plates for cleat retention and enhanced proprioception. And for long-lasting traction on trails, slip-resistance in water, and toe protection, you can rely on the Boa boot's molded Vibram Idogrib rubber outsole with 4 millimeters of self-sharpening, multi-directional lugs.

Replaced My Last Simms Boa Boots

  • Familiarity: I've used it several times

I just replaced my felt sole Boa boots with these new Simms boots. Love the side placement of the Boa mechanism and the rubber treads with stud options.

My last boots gave out with the felt sole coming apart and the Boa lace wire starting to fray and clog up the guide system. These boots are just as sure footed as my felt boots and the Boa mechanism on the side is more out of the way and less likely to get the direct wear and stress pressure of my walking movement.

  • Familiarity: I've used it several times

These shoes are awesome! I had the Simms rivertek boot with the boa before and decided to try these out. These boots are a lot lighter and the boa system tightens around the ankles better. It is also a lot easier to get your foot in them.

Get it

    LOVE the boa system on these. Super simple lace up and stays put all day. Super duper durable. Simms pulled through again

    • Familiarity: I've put it through the wringer

    He would rule the galaxy in the boots! I love the easy Boa system and they pull snug on the foot for a great comfortable fit. Very durable I have put these thru the ringer and love them. No more wet muddy cold laces in the spring and winter. The reliability and quality you come to expect from Simms.
