Shamma Sandals Review: Wide, Adjustable, and Built to Move 。TrailStar Omegas are designed to give you the most protection for the toughest trails. The thicker sole of the Omegas bridges the gap and creates consistency with every step. These adventure sandals excel under heavy load and are perfect for backpacking and rigorous terrain. When absolute control and stability is required, the TrailStar Omegas are always up to the task. SOLE TrailStar Omega soles are made from a composition of 8mm Vibram® Newflex and 6mm Vibram Morflex. Omega is our thickest and most protective sole. This creates a sole that provides excellent protection for your feet while still being light and responsive. The aggressive tread of the Vibram Newflex makes navigating rough terrain and trails a breeze while the Vibram Morflex gives you a firm yet cushioned place for your feet to rest. Choose between an UltraGrip or a Cognac Aniline Cowhide Leather footbed for a 15mm total stack height. MADE IN THE USA! Proud to be made in the USA! All sandals are made in Santa Cruz, CA by a small team, using primarily US sourced materials along with high quality components from Italy, Germany, and other international partners.
