Foot Profile

badminton fit reference · rev 2026-06-29

Source of truth for foot geometry → shoe sizing. Derived from self-measurement + two top/sole photos (2026-06-29). Re-measure heel-to-toe when convenient (see footer) to firm up the length figure.

TL;DR spec

Egyptian (big toe longest)

Forefoot width

8.8–9.2 cm (unloaded→loaded)

Heel

comparatively narrow

Arch

normal / medium

Width class

ratio ≈ 0.36 → narrow–medium

Length (measured)

~25 cm (verify)

Recommended size

Asics US 8 → 8.5 fallback

Fit variant

Asics standard "D" width

Model

Asics Gel-Rocket 12

Fit to

right foot (lead foot)

Measurements

Geometry schematic — not to scale. Numbers from self-measurement.

Metric	Unloaded (leg raised)	Loaded (weight on)	Use
Forefoot width (ball)	8.8 cm	9.2 cm	governs width fit
~3.5 cm above ankle	8.8 cm	9.2 cm	heel/ankle region (minor)
Length (toe→ankle, as measured)	~25 cm		verify heel→toe

Loaded width is the number that matters — the foot spreads under landing/lunge load, so fit to 9.2 cm, not 8.8.

Shape read (from photos)

Egyptian toes: big toe clearly longest, the rest step down progressively. Needs length headroom + a rounded toe box; a pointed/tapered last (some Victor models) would crush the big toe.
Medium forefoot, narrow heel: classic mismatch — size for the forefoot, then lock the heel with lacing so it doesn't slip.
Normal arch: stock insole is fine; no special arch support needed.

Sizing logic

Yonex men's chart (internal cm length):

UK	cm	EU	note
7	25.5	40	current HY Ultra-i → toes jam (right foot)
7.5	26.0	40.5	primary pick — ~0.5 cm clearance, heel still locked
8	26.5	41	fallback — ~1 cm clearance if 7.5 still short after long play
8.5	27.0	41.5	too long — heel will slip

Why UK 7 jams: internal length 25.5 cm ≈ your foot length → near-zero toe gap. Add session swelling + forward slide on lunges + an Egyptian big toe + lead-foot load = big toe hits the wall. Fix is length, not width.

Yonex guidance is foot-length + 0.5–1 cm. You currently have ~0. Buy both 7.5 and 8 if the seller's return policy allows, fit to the right foot, keep the one that clears without slipping.

Asics sizing

Asics uses US sizing on its own last — ignore the UK number, size by cm of foot length, leave 0.5–1 cm clearance at the toe.

Foot length	Asics cm	US (men)	UK	EU
~25.0	25.0	7	6	40.5
~25.5	25.5	7.5	6.5	41
~25.5–26	26.0	8	7	41.5
≥26	26.5	8.5	7.5	42

Asics fit notes for this foot:

Target 26.0–26.5 cm internal. Do NOT go US 7.5 — that's foot length with ~zero gap, i.e. a repeat of the Yonex UK7 jam.
Asics runs slightly narrow in the forefoot and generally true-to-size → good for a narrow-medium foot. Standard "D" width; not 2E wide.
Men's Asics can run a touch large and the heel can slip; with a narrow heel, size up for toe room and lock the heel with the runner's loop rather than sizing down and re-jamming the toe.
Decision rule: remeasure heel-to-toe (both feet, larger one). ≤25.0 → US 7.5 | ~25.5–26 → US 8 | ≥26 → US 8.5
Gel-Rocket and Gel-Blade size identically; Gel-Blade has a bit more cushion for hard lead-foot landings.

Target fit (the toe-gap principle)

The gap in the diagram is created by choosing the right size, not by the shoe having a long nose.

The 65Z4's external toe cap looks short in product photos because of its rounded Toe Assist Shape — that's the outside shape. Internal length still follows the cm chart. Don't judge fit from the photo silhouette.

Heel-lock lacing (runner's loop)

Lace normally to the 2nd-from-top eyelet, both sides.
Feed each lace straight up into the top eyelet on the same side → makes a vertical loop.
Cross each lace and thread it through the opposite loop (green).
Pull down + out → loops cinch onto the ankle.
Tie off.

Pins the narrow heel back so the foot can't slide forward into the toe box. Lets you safely run UK 8 without sloppiness.

Alternatives (cross-brand)

Ranked for this foot profile: narrow-medium width, narrow heel, Egyptian rounded toe, hard lead-foot landings.

Shoe	Fit for profile	Cushion / landing	Verdict
Asics Gel-Rocket 12	narrowish, rounded toe	GEL shock absorb	CHOSEN best value
Yonex 65Z3	snug, same family last	good (Power Cushion+)	easiest like-for-like swap
Mizuno Wave Fang / Fang Pro	snug "D", enveloping, strong heel hold	Wave + AP+	best for the narrow heel
Yonex Eclipsion Z3	65Z-like fit, thicker padding	max stability, heavy (~367g)	fortress lateral support
Yonex Aerus Z2	snug / narrow	light (~240–270g), LESS cushion	speed, not landings
AVOID Yonex Comfort Z3 (wider fit) \| most Victor / Li-Ning (wide lasts), except narrow lasts e.g. Victor A970

Decision

PRIMARY: Asics Gel-Rocket 12 — standard "D" width — US 8 (US 8.5 fallback) — fit to right foot — heel-lock laced.
Narrow-forefoot fit, GEL cushioning for hard lead-foot landings, value + availability. Size by cm, not UK number.

ALT (Yonex family): 65Z3 / 65Z4, Men's standard fit, UK 7.5 (8 fallback). Toe Assist cap suits Egyptian toe. Same heel-lock lacing.
