How to fit your insoles
Will these crowd my toes inside steel-toe boots?
No. Remove your thin factory insole first. While the LOADLOCK™ heel cup and TPU arch are heavy-duty, the forefoot tapers down to 2.5mm, designed to help preserve toe space under steel or composite safety caps. Fit varies by boot.
How do I size and fit them to my boots?
Select your shoe size bracket (XS to XL) so the TPU arch bridge matches your foot length. Pull out your old factory boot liner, lay it on top of LOADLOCK™, and if your boot has a shorter or square toe box, follow the 3 molded under-toe guide grooves with scissors for a flush lock.
How does the 60-Day Concrete Shift Guarantee work?
Wear them on concrete for up to 60 days. If your heels, knees, or lower back still burn after a full shift, email us for a 100% refund—even if the insoles are sweaty, trimmed, and worn.
