ASICS Lethal Relentless Rugby Boots
The ASICS Lethal Relentless rugby boots are built for Rugby Union players who need serious traction when the ground softens up. Designed with removable metal studs and a stable, supportive platform, these boots suit competitive school, club and senior players who play through winter conditions.
Underfoot, the FLYTEFOAM™ midsole works with ASICS HG10mm™ technology to reduce load through the lower limbs and keep things comfortable across long training sessions and match days. Rearfoot GEL™ cushioning helps absorb impact on hard tackles and repeated sprints, which makes a noticeable difference late in the game.
The outsole uses a proven triple-density construction with an 8-stud layout, including 6 removable metal studs for strong grip in soft and muddy conditions. Flex grooves through the plate help the boot move more naturally, supporting smoother transitions when accelerating, changing direction or getting out of contact. This tooling is based on the trusted Lethal Tight-Five platform, updated for modern play.

FAQs
Are these boots suitable for all rugby?
The removable metal studs are designed for soft and wet natural grass surfaces.
Do the studs come off?
Yes. The boot features 6 removable metal studs so you can replace them as needed.
Are these good for forwards?
They’re a strong option for forwards due to the stable platform, traction and impact protection, but backs who play on soft ground will benefit too.
