Pilgrim Surf+Supply 【Shop Exclusive】mont-bell / Lock-on Sandals Size: M (25-26 cm) I bought these to wear at the beach and in the mountains this summer, but I didn't go at all and they've remained unused after only a few wears, so I'm putting them up for sale. Features a unique strap design. The "Lock-on Sandals" provide enhanced stability with a back strap that secures the heel. The distinctive S-shaped thong firmly holds the instep, preventing the heel from lifting while walking. They are lightweight and offer a cushioned, soft feel. These versatile sandals are perfect for outdoor activities and everyday wear.
