Loosen the laces sufficiently before fitting and look at the tongue. Does it lie freely between the sides, or do folded panels connect it to the upper? Product descriptions often call the latter a gusseted tongue. SCARPA lists one on particular trekking models, for example. The term describes a construction rather than the properties of every walking boot.
Open the entry without force
A connected tongue cannot be pulled forward indefinitely. Release the lacing as intended first. If inserting your foot still requires considerable force, ask about handling and reassess the fit. Avoid pulling hard on thin folds or a small loop whose purpose you have not established.
Notice where the side connection ends. Its visible height does not allow you to assign your own waterproof rating. That depends on the complete construction of the particular model. Connected upper fabric and a tested waterproof system are different things.
Arrange the folds when fastening
Insert your foot, center the tongue and arrange the side panels so they do not form a thick bunch beneath a tight crossing. Fasten progressively. If one area feels unusual, open the boot again and see whether a fold has been displaced.
Walk for several minutes afterwards. Does the tongue remain in its intended position? Can you move the upper on a step without an uncomfortable pull from a panel? A small construction detail can matter more in motion than when examining an empty boot.
Tongues do not all need the same thickness or symmetry. Models have different designs. Look for the manufacturer's explanation before treating an unfamiliar shape as a defect or exceptional equipment. What matters is how that particular component works around your foot.
Look again after the walk
When taking the boots off, loose stones or dirt may be visible around the folds. Remove them gently according to the care instructions before putting the pair away. Check visible seams and material without pulling at the connections.
Ask a retailer to assess a damaged side panel. An arbitrary adhesive strip may alter movement and complicate later repair. For a future purchase, this gives you another specific question: how easily can the entry be opened, arranged and fastened again in regular use?
