Alternative: how to fit fins one-handed
Set up straps non-symmetrical (do once for each fin)
- Someone else may need to do this but it is only done once.
- Wet fins.
- Slide strap through ankle slots to give minimum strap length to outside buckle to fit your leg. This leaves maximum strap length to inside buckle.
- Strap outside buckle as normal to fit your leg securely.
- Strap inside buckle very loosely, so only a little strap tail pokes out of the inner slot.
Put on fins by tightening inside buckle
- Wet fins.
- Slide your foot through both strap loops together.
- Centre the fin tip near your second toenail.
- Tighten inside buckle by pulling strap tail hard with one hand so that it slips through the buckle and tightens around your leg.
- Tidy strap tail under strap.
Take off fins by loosening (but not fully releasing) inside buckle
- Wet fins.
- Pull out strap tail from under strap at inside buckle.
- Keep pressing arrow gently to unlock inside buckle (without pressing finger against strap).
- Pull strap firmly so it slips through both buckle slots together (don’t pull it right out).
- Slide fin off your foot.
- Leave inside buckle loosely done up (outside buckle is still done up tight).
