RM Williams boots rely on leather tension and elastic recovery as they dry and reform after wear.
Without internal support, the vamp relaxes as moisture leaves the leather. Over time, this leads to deeper creasing, loss of shape, and unnecessary stress on the elastic.
RM Williams boots rely on leather tension through the vamp and elastic recovery at the sides as they return to shape after wear.
As the boot comes off the foot, the leather relaxes inward and the elastic contracts. Without internal support, this recovery happens unevenly, concentrating stress across the upper and instep. Over time, this leads to deeper creasing, stretch, and a gradual loss of structure.
Trimly’s Premium Boot Trees are shaped to support RM Williams boots during this recovery phase, guiding the vamp, instep, and heel back to their intended shape as the leather reforms.
