Two letters at the end of the name change the whole load case: OC, outdoor clay. Same chassis as the standard Solution Speed FF 4, different ground contact, and the ground is the only part of a shoe that has to solve a materials problem every single step.
The midsole is FLYTEFOAM, softer in this generation, delivering cushioning and a high energy return at low mass — foam density is where a shoe wins or loses its weight budget, and they spent it well. SPEEDTRUSS runs through the structure to improve quickness and cutting motions.
Underfoot it is a PRECISION SOLE with ASICSGRIP compound on a clay-court outsole: traction without giving up durability, which on a granular surface is a genuine engineering compromise, because grip normally costs you rubber.
There is a polyurethane loop and eyelet loops on the medial side of the upper, added for one reason — laces fail on the inside edge during abrupt lateral movement, so that is where the reinforcement went. And the sockliner is made with a solution-dyeing process that cuts water use by about 33% and carbon emissions by about 45% against conventional dyeing.
This colourway is White/Black.
Mogadishu is a masonry city and I could look at it all week. The Fakr ad-Din Mosque in Xamar Weyne was standing by 1269, with a domed mihrab — a dome in the thirteenth century means somebody understood compression and thrust with no way to calculate either.
The Arba'a Rukun Mosque in Shangani went up in the same decade in coral stone, which is quarried wet, cut soft and hardens in air; the whole coast is built from a material that sets after you have shaped it.
The ruined Mogadishu Cathedral is a Gothic shell open to the sky, and with the roof gone you can finally read the load path, which is a terrible way to be given a good section drawing. Then Lido Beach and the old Secondo lighthouse along the shore, still doing the simplest engineering job there is: be visible.
“A dome from 1269 with no arithmetic behind it. That is the proof.”
They built it, and it is still up.
Clay outsole on clay, and reinforcement exactly where the failures were. I approve of this shoe.
