Padding is read with a depth gauge on an uncompressed pair at two fixed points: the centre of the ball of the foot and the centre of the heel seat. Flex angle is the angle the forefoot reaches when the sole is bent by hand against a held heel and kept there for three seconds. Both are averaged over three pairs in size EU 38 and rounded to the nearest whole unit. The full method.

Try them on carpet indoors. A pair with outdoor wear on the sole cannot be returned. This does not affect your legal guarantee if the pair turns out to be faulty.

What this pair is

The back is open and a strap crosses the heel, adjustable over five holes across a 32 mm range.

An open back removes the heel counter, so the strap tension is the only thing holding the heel down onto the 14 mm of padding under it. Set it snug rather than tight.

Padding and flex match the closed 35 mm pair: 10 mm forefoot, 14 mm heel, 24 degrees.

Break-in

Two to four wears. Start one hole looser and tighten once the strap has taken its set.

Care

Wipe with a dry cloth after wear. Use a neutral leather cream every eight to ten wears and let it absorb for twenty minutes before buffing. Dry away from direct heat. Full care guide.

The country of manufacture is printed on the label inside the left shoe and on the box. We make no origin claim in our product copy.
