A weight-based slider LoRA for Krea 2 that dials foot size on male subjects. There are no trigger words — load it, set the weight, and generate: 0 = off, positive = bigger, negative = smaller. It works on bare feet, socks, and shoes; footwear scales along with the foot.
Usage
Trained on Krea-2-Raw; intended to run on Turbo.
Built for and tested on men. On female subjects the effect is weak and unstable — that's by design, not a bug to report.
Strength guide (v2)
The relative strength varies by footwear: it's strongest on bare feet, then socks, then shoes. In one measured comparison, matching the same visible size change took roughly bare +0.7 ≈ socks +1.1 ≈ shoes +2.0 — but how smoothly the size responds varies with the other parameters of the image, and the response is not always linear. Treat these reference numbers as a starting point.
Bare feet: +0.75 to +1.0 is the reliable range. Toes are the first thing to degrade at higher weights — reroll if they misbehave.
Socks: clean to about +1.5; around +2.0 the sock volume goes soft.
Shoes: the most headroom — coherent up to +2.0.
Negative weights shrink socks and shoes cleanly. One caveat: on bare feet the shrink direction is much weaker — if you specifically want smaller bare feet, v1 handles that better.
What to expect across a sweep
The sample strips show the same seed swept across weights. Use them to calibrate expectations in two ways: how much the feet change, and how much everything else does. Experience shows that composition drift across a sweep is limited to small incidental changes (décor details, minor framing) rather than large or biased ones.
Versions
v2 (recommended): single-file contrastive build. Bidirectional, much better composition stability across the dial, style-neutral at 0, half the file size.
v1: the original difference-of-LoRAs build, usable range −1.5 to +1.6. Kept mainly for one niche: it shrinks bare feet better than v2 does.

Description
One file, no trigger words: 0 = off, + = bigger, − = smaller. Recommended ~1.0; bare feet like it lower (+0.75–1.0), socks are clean to ~1.5, shoes to ~2.0. The shrink direction works well on socks and shoes, less on bare feet (v1 is better there). Trained with a custom per-step contrastive trainer on ~50 pixel-aligned before/after pairs (rank 16, on Krea-2-Raw, run on Turbo). Compared to v1: much more stable composition across the dial and a style-neutral zero.
