FootJoy Upper Technology explained...

Calfskin Leather Uppers
Calfskin is the finest shoe leather in the world. Premium calfskin offers unparalleled beauty, fit, and resistance to stretching.
ECL™ Leather System
Developed with Pittards® of England, this proprietary process ensures maximum waterproof protection and increased breathability without the need for a membrane.
Full Grain Leather Uppers
Offers outstanding waterproof comfort, breathability, and durability.
Proofguard™ Waterproof Membrane The Proofguard membrane provides total waterproof protection.
Easy Care Synthetic Uppers
GreenJoys' synthetic leather or PVC (poly vinyl chloride) offers soft, easy care water resistance with the look and feel of leather.
Intellishield Extreme™
The Intellishield Extreme membrane provides temperature responsive waterproof protection and breathability. When the in-shoe temperature rises, the pores of the Intellishield Extreme membrane open to allow heat and moisture vapour out. When in-shoe temperature falls, the pores close to insulate. All this temperature responsive action happens while remaining totally waterproof.
BOA Lacing System™
Unlike traditional laces, this lacing system allows you to dial in for a more precise and consitent fit.
Interlocking Lace System
LT Series' interlocking lace system works with the TPU heel cup for added comfort and stability.

FootJoy In-Shoe Technology explained...

Welt Construction
A classic shoe construction technique which involves stitching the upper, a sculpted platform of Poron® and cork, and the outsole together. This provides the most exact and consistent fit round after round.
Slip Last Construction
A shoe construction technique often found in running shoes. This unique construction allows a shoe to be made without an insole board, producing a more contoured underfoot platform and vastly increased flexibility.
Leather Insoles with Poron®
Leather insoles provide elegance and durability while Poron urethane offers underfoot shock absorption and resiliancy.
Dryz® IntelliTemp™ Management System
Dryz® IntelliTemp™ Technology (located in the tongue and Fit-Bed®) is an interactive temperature and moisture management system. This material regulates the in-shoe temperature by storing heat in microscopic capsules called Intellisorb™. IntelliTemp also wicks moisture away into a gel layer contained within the Fit-Bed. The result is an in-shoe environment that is cool and dry.
GelCollar™
GelCollar is a visco-elastic gel molded to match the shape of the ankle. The technology provides additional comfort and support around the collar. GelCollar also contains IntellTemp™. This technology stores heat away from your foot, keeping you cool while you play.
Super Soft PU Linings
PU (poly urethane) linings look and feel like leather and provide excellent fit and comfort.

FootJoy Outsole Technology explained...

WaterLoc™ Outsoles
WaterLoc outsoles features a combination of leather for support and TPU (thermal plastic urethane) for forefoot walking flexibility.
Wishbone Suspension
Patent-pending technology that allows the outsole to mimic the foot's natural axial rotation. The result is an outsole that functions as an independent suspension, remaining in contact with the ground regardless of lie.
GelRide™
GelRide is a shock absorbing gel placed in the heel cavity of FootJoy GelFusion shoes for added cushioning.
P.R.O. ™ (Platform Responsive Outsole)
Two-pod outsole featuring an aluminised fibreglass midfoot stability bridge.
Stability Bridge™
Midfoot TPU (thermoplastic urethane) insert for additional platform stability and support.
OptiFlex™ Technology
The OptiFlex forefoot flexibility channel is softest density of TPU (thermal plastic urethane) used in tri-density TPU outsoles. OptiFlex produces unparalleled walking comfort and flexibility.
EVA Midsoles
EVA (ethyl vinyl acetate) midsoles provide lightweight cushioning underfoot. EVA does not take a set, so the cushioning will remain constant for the life of the shoe.
Tri-Density TPU Outsoles
Varying densities of TPU (thermoplastic urethane) are strategically placed throughout the outsole for stability, flexibility, and walking comfort.
DuraMax™ Rubber Outsoles
DuraMax is a proprietary rubber compound that provides turf gripping performance and durability.
Fast Twist System™
The Fast Twist System (FTS) is the most preferred cleat insert system on the market today. One-quarter turn secures and releases the cleat for quick changing.
Pulsar cleats by Softspikes
The #1 selling cleats in golf features Dynamic Cleat Technology™. DCT provides superb turf grip, walking comfort, and green friendliness.
