I fully agree. I used to not have gloves, but the main problem is that once it starts to bleed, it will bleed through even ghe glove, and that is not popular in sparring session. It happaned that I realized that everbodies gi is covered with red dots, and its first when i take off my golves i realise blood gets out of the fingers of the glove.
I have tried probalby 5 different gloves and they one i have not is not percet, but its the best so far. It's a leather glove made for the bag with cut off fingers, it prefere a slightly thinner one but havent found one so far.
I also tries boxing wrap but that amke your hand feels like they are int cast and it gives unnormally high wrist support, that allows you to strike very sloppy. However inside a bloxing glove owhere you really cant' form a proper first, it might be necessary to make up for the lack of a fist stabilization.
So during my hand conditioning I realized that the callous has 2 main types. The one that is close to the bone and one that floats above the bone (imagine a callous on top of a blister).
When I condition my knuckles, I always check to make sure that the Callous is not floating. This type of formation pads your knuckles but does not protect against ripping the skin. In this situation the callous strikes the bag but the fist stills moves.
I guess a better visual is like your fist sliding around in your glove causing the same outcome that you tried to prevent on the bag. Now think of your skin like a glove and the callous the padding and your skin still gets damaged not because of the impact but because of the sliding.
The light knuckle tapping that I use to condition my hands prevents that "floating callus"
Some of you might have seen photos of boxers where the callus rips of the skin. That's the bad callus that you don't want. The one that is closer to bone doesn't move around when the hand is opened flat.
This is probably a better read of what I tried to explain
Ai Written:
There are
two different tissue states that fighters, climbers, rowers, and runners all experience:
Ai Response:
A. Pressureāinduced hyperkeratosis
This is the medical term for the āanchored, closeātoātheāboneā callus.
It forms when:
- the skin is repeatedly compressed
- the epidermis thickens
- the deeper layers stay bonded
- the tissue becomes dense and protective
This is the good callus.
B. Shearāinduced epidermal separation
This is the medical term for the āfloating callusā you described.
It forms when:
- the skin layers separate due to friction
- a blister or microāblister forms
- the outer layer hardens over the separated tissue
- the callus is not anchored and can slide
This is the dangerous one that tears.
My question to Ai: What's the relation to impact and friction?
1. Impact and friction create
This is the core truth:
Impact ā Compression ā Bonded callus
Friction ā Shear ā Floating callus
They are not the same stimulus, and the skin does not adapt the same way.
Letās break them down.
2. IMPACT = Compression = āBondedā callus (protective)
Impact creates
vertical force into the knuckle.
This causes:
- the epidermis to thicken downward
- the dermis and epidermis to stay tightly bonded
- collagen to align and stiffen
- the tissue to compact
Medical term:
pressureāinduced hyperkeratosis
This is your:
- āclose to the boneā callus
- āanchoredā callus
- ātrue conditioningā callus
It protects you because
all layers move together on impact.
There is
no sliding, so no tearing.
3. FRICTION = Shear = āFloatingā callus (dangerous)
Friction creates
horizontal force across the skin.
This causes:
- the epidermis to slide over the dermis
- microāseparation between layers
- fluid or damaged tissue to form between layers
- the top layer to harden over a weak base
Medical term:
shearāinduced epidermal separation (or blisterāderived hyperkeratosis)
This is your:
- āfloating callusā
- ācallus on top of a blisterā
- āunstable padā
It tears because
the top layer stops but the deeper layers keep moving.
Exactly like your glove analogy.
4. The relationship between impact and friction is this:
Impact builds callus.
Friction undermines it.
Impact = compression = bondingFriction = shear = separation
They are
opposite forces acting on the same tissue.
This is why:
- you can have strong knuckles but still rip skin
- you can have thick calluses that fail under shear
- you can condition bone but still damage the epidermis
Impact strengthens. -
Friction destabilizes.
5. Why fighters get confused
Because both impact and friction can produce
thickened skin, but:
- one is anchored
- one is floating
Thickness ā stability.
My Question to Ai: So, impact would be striking directly into a heavy bag and friction would be striking across the bag?
Ai Response:
Yes ā thatās exactly the right way to think about it, and youāre not misunderstanding anything.Let me give you the
clean, mechanically accurate breakdown using your example.
1. Impact = straightāin strike = compression
When you hit a heavy bag
directly into it, with the force going
into the bag, the skin experiences:
- vertical force
- compression
- no sliding
- no shear
This produces the
bonded, protective callus (pressureāinduced hyperkeratosis).
All the skin layers move
together on impact.
This is the good kind.
2. Friction = glancing strike = sliding across the bag
When your fist
slides across the bag ā even slightly ā the skin experiences:
- horizontal force
- shear
- microāmovement between layers
- epidermal separation
This produces the
floating callus (shearāinduced epidermal separation / blisterāderived callus).
The top layer stops.The deeper layers keep moving.Thatās what causes tearing.
This is the dangerous kind.
