The raised collar carries the upper above the ankle line, changing how the boot sits and how it feels going into a sprint, while the firm-ground soleplate underneath is specified for natural grass. This is the Mint\/Navy\/Lemon colourway, product code KJ3420, in UK sizes 6 to 8.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMid-cut collar:\u003c\/strong\u003e The upper extends above the ankle rather than finishing at it, the defining difference from the standard League FG.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirm-ground soleplate:\u003c\/strong\u003e Studs configured for natural grass pitches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeague tier:\u003c\/strong\u003e One step above Club in the F50 range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eF50 speed last:\u003c\/strong\u003e The narrow, low-profile shape used across the F50 line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaced closure:\u003c\/strong\u003e Full lacing beneath the collar for midfoot adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance Overview\u003c\/h2\u003e\n\u003cp\u003eA mid collar is a preference, not an upgrade.
