Dr. Martens Maybole MJ Square Toe Mary Jane Shoes Worn Once. Be square. The Maybole MJ shoe is an unconventional take on the classic heeled Mary Jane silhouette. An extended, angular new sole emphasises and exaggerates the square toe upper. The low-profile sole is marked with our signature grooving pattern, with distinctive corners around the outside of the heel. The strap is secured with a single, adjustable branded buckle. Arcadia is a high-shine leather with a base dye and contrasting topcoat, which rubs off over time to reveal the underlying colour. Care with Dr. Martens Shoe Polish in neutral or colour as appropriate.
