Korkers Greenback Review: Two Soles, One Boot
Buy them if you fish rivers with different rock and different felt regulations and want one boot that legally and physically handles both. Skip them if you fish one river forever, because a fixed sole boot has fewer parts to fail and interchangeability you never use is complexity you paid for.
Felt and Kling-On rubber in the box, and the trade that interchangeable soles actually make.

What it does well
- Two soles in the box means you are not choosing between grip and legality at purchase, you are choosing at the truck.
- A published weight, which almost nobody else in this category gives you: 2 pounds 7 ounces per pair in size 9.
- Drainage ports are not a gimmick. A boot that sheds water is a boot you can walk a mile back to the car in.
- Faster drying genuinely reduces the risk of moving organisms between watersheds, which is the reason felt is restricted in the first place.
Where it falls short
- More parts means more failure modes. The OmniTrax attachment is the thing owners worry about, and a sole that detaches mid river is a worse problem than a sole that grips slightly less.
- Interchangeability only pays if you use it. If you fish one river with one kind of rock, you have bought a mechanism you will never operate.
- At 2 pounds 7 ounces per pair in size 9 this is not a light boot, and boot weight is what you notice on a long walk in rather than in the water.
- Felt is restricted in several states and provinces. Owning a felt sole does not make it legal to fish, so check your local rule before you use it, and that rule comes from your fish and wildlife agency rather than from the box.
What owners report
Published owner reviews of the Greenback are consistent that the interchangeable system works and that the two included soles are the reason people buy it. Owners who fish across state lines are the most positive group, and the drainage design draws repeated specific praise from people who walk a long way to their water.
The recurring concern in published reviews of Korkers boots generally is the sole attachment. Reports of soles loosening exist alongside a larger number of reports of the system working fine for years, which is roughly what you would expect from any mechanism. Checking the sole is seated before you get in the water is the sensible habit.
How it fits with the rest of your kit
The question this boot answers is the sole material one, and it is worth understanding what you are choosing between. The felt against rubber grip comparison covers what each does on algae and wet stone, and the felt against rubber comparison covers the legal and invasive species side, which is the part that decides the question in a growing number of states.
Boots are half a purchase. The Simms Tributary and Simms Freestone waders are the stockingfoot halves reviewed here, and the wading boots roundup covers the cheaper fixed sole field. For a straight fixed sole rival at a similar level, the Simms Freestone boot is the comparison worth making.
Who it suits
- Anglers who travel between states or provinces with different felt rules.
- Anyone fishing both slick bedrock rivers and freestone cobble in the same season.
- People who walk a long way in, where drainage and drying time genuinely matter.
Who should skip it
- Single river anglers, who are better off with a fixed sole and fewer parts.
- Weight sensitive walkers, since 2 pounds 7 ounces per pair in size 9 is mid weight rather than light.
- Anyone who will never actually swap a sole, which is more people than admit it.

Frequently asked questions
Are Korkers interchangeable soles reliable?
Broadly yes, and the concern is legitimate rather than imaginary. Published reviews contain both long term success stories and reports of soles loosening, which is what you would expect from any mechanism with moving parts. Check the sole is fully seated before you step into the water, the same way you would check a wading belt, and treat the system as something to inspect rather than to forget.
Korkers Greenback versus Simms Freestone boot, which should I buy?
Take the Korkers if you fish more than one kind of river or more than one state's regulations, since both soles come in the box. Take the Simms if you fish one place and want the simplest possible boot with the most durable upper, and tune grip with studs instead. The Simms costs more and has nothing to detach.
Is felt banned where I fish?
It may be. Several states and provinces restrict felt soles because felt holds water and can transport invasive organisms such as didymo between watersheds, and the list changes over time. Your state or provincial fish and wildlife agency is the authority on this, not a gear review, so check the current regulation before you use the felt sole this boot ships with.
Do interchangeable soles grip as well as fixed ones?
The sole material does the gripping, so a felt sole on a Korkers boot grips like felt and a rubber sole grips like rubber. What the system adds is an attachment interface, which adds a small amount of stack height and a part to inspect. The grip difference against a fixed sole of the same material is not the reason to choose one over the other.
What size Korkers should I order?
Wading boots go over a neoprene stockingfoot, so usually one full size above your street shoe and sometimes more with a thick sock. Korkers publishes a weight of 2 pounds 7 ounces per pair in size 9, which is useful for comparison but not for sizing. A boot too small compresses the neoprene and makes your feet cold, and one too big lets your heel lift on a river bed.
How we choose: we compare published manufacturer specifications, line and leader standards, and verified owner reviews across retailers. We do not test gear in person, and every diameter, grain weight and breaking strength quoted here is the manufacturer's published figure unless we say otherwise, so check the spool label before you trust a number. Nothing here is professional instruction. Wading moving water is the real hazard in this sport: wear a snug wading belt, know the water temperature, and turn back rather than push through a crossing you are unsure of.
